An isosceles triangle has a measure of 70o what is the measure of each base angle?
To figure out what the measure of the base angles in an isosceles triangle are, it is important to first understand several things about an isosceles triangle. 1. A triangle has 180 degrees. 2. An isosceles has two equal sides, which means that it also has two equivalent angles. 3. In knowing at least any one angle of an isosceles triangle, it is possible to figure out the other two. Since the base angles are unknown in this question, and they are equivalent to one another, it is a simple algebraic problem. 180 - 70 = 2A 180 is the number of degrees in a triangle 70 is the number of degrees taken up by angle C, with angles A and B being the equivalent base angles. 2a is the double of one base angle. Let's solve. 180 - 70 = 2A 110 = 2A 110/2 = A 55 = A The measure of each base angle is 55.
In what way does knowing the measure of the three sides of a triangle tell you more than just knowing the measures of the three angles?

How do you find out if a triangle is a right triangle without knowing any of the side lengths?
well if its a perfect L you should be able to see it! hope i helped =)
How do you find the angles of a hepatagon?
Simple, by finding how many traingles there are in the shape through this formula 180(n-2). N stand for how many interior angles. Knowing how many triangles you can multiply it by 180 giving you the total degrees in the shape. Keep in mind this is only for a REGULAR hepatagon. Knowing the sum of the angles u can divide it by the total amount of angles and get the measure for each interior angle. This sounds confusing but it really isn't.
An isocleles triangle has one angle witch measures 66 what is the measures of the other two?
In an isosceles triangle there are two equal sides and two equal angles. In a triangle ABC, if angle A is between the sides of equal length, then angles B and C are equal.Without knowing which angle (A, B or C above) is 66o there are two possible answers:If the 66o angle is between the two sides of equal length (angle A) then the other two angles (B and C) are (180o - 66o) / 2 = 57o each.If the 66o angle is not between the sides of equal length (angle B or C), then the other two angles are 66o (the other angle of C and B) and (angle A) 180o - 66o x 2 = 48o.
How do you classify a triangle knowing all the sides?
scalene, equilateral, isosceles and right angle triangles
If the two sides of an isosceles triangle is 5 cm then what is the third side?
that question can not be answered without knowing what the inside angle of the 2 equal sides is.
What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 42?
If you are dealing with an isosceles triangle, if one of the base angles measures 42 degrees then the other base angle measures 42 degrees. (By definitioin an isosceles triangle has at least 2 equal sides and the angle opposite those sides with be equal.) If you add up the degrees in each angle within a triangle, it will always equal 180 degrees. Knowing all this you can set up a formula: Angle 1 + Angle 2 + Angle 3 = 180 42 + 42 + Angle 3 = 180 Angle 3 = 96 degrees
How do you find the sides of a right angled isosceles triangle when you know the angles?
You cannot. A right angled isosceles triangle will always be 90-45-45 so knowing the angles does not add any information. Without knowledge of any one side, you cannot distinguish between the infinitely many similar 90-45-45 triangles.

How do you draw a triangle with an area of 6cm2?
To draw a triangle with an area of 6cm², you need to determine the base and height of the triangle. The formula for the area of a triangle is 0.5 * base * height. So, if the area is 6cm², you could have a base of 4cm and a height of 3cm, or a base of 6cm and a height of 2cm. Once you have the base and height values, you can draw the triangle with those measurements.
How do you find the base and height of a triangle if you only have the hypotenuse?
I'm pretty sure that only works if it is an isosceles right triangle. In that case, use the Pythagorean theorem to calculate the base and height knowing only the hypotenuse. A2 + B2 = C2. A=B= height= base. C= hypotenuse
How do you use formula of a triangle?
There are many formulae for triangles: Some formulae will calculate sides given angles or conversely. Some will calculate the area. It is not possible to say how you would use a formula without knowing what it is for!
How do you find angles of a triangle?
I cannot answer this without knowing any more information. Finding the proper dimensions of a triangle without knowing the kind of triangle cannot really be done. Because it may be an isosceles triangle (every angle is equal) or it could be a 30-60-90 triangle etc.
How do you find lengths of sides of isosceles triangle if vertex angle is 15 degrees?
You require another piece of information. Knowing the "vertex" angle will not tell you the length of any one side. You can have a triangle the size of the continental USA with a "vertex" angle of 15 degrees and you can have a triangle invisible to the human eye with a "vertex" angle of 15 degrees. You can see how these would have different side lengths.
What is the angle measure for a triangle?
The angle measure of a triangle is dependent on the type of triangle (scalene, right, isosceles, or equilateral) and also the measures of the other two angles.In a scalene, none of the angles can be predicted without a protractor because none of the angles are equal.In a right triangle only one angle can be undoubtedly determined, the 90° angle (right angle). Knowing this angle's measure, this only limits the possible angle measures of the other two angles. (They must each be less than 90°, but together sum up to 90°)If you know one of the base angles of an isosceles triangle, by the Isosceles Triangle Base Angles Theorem, the other base angle will be congruent. To find the last angle, add the base angles together and then subtract that number from 180.The only triangle that has angle measures that can be determined just by its name is an equilateral, all angle measures equal 60°.
Can you determine the type of a triangle by just knowing it's sides?
Yes. The three sides uniquely specify the triangle. If all three sides are equal it is equilateral. If only two are equal it is isosceles. If none are equal it is scalene. If the sum of the squares of the two shorter lengths is equal to the square of the longest length, it is a right angled triangle. If the sum of the squares on the two shorter sides is less than the square on the longest, it is an obtuse angled triangle. Otherwise it is an acute triangle.
