How can you find the length of the 2 sides of an isosceles triangle when you know the base and the height?
By using Pythagoras' theorem.
If you have the width and height of a triangle how do you get the third length?
Really you don't have enough data to calculate this.The height is not necessarily one of the three sides. The height is perpendicular to the width.If the triangle has a right angle, and you know two of the sides, you can calculate the third side using the rule of Pythagoras (a squared + b squared = c squared).Really you don't have enough data to calculate this.The height is not necessarily one of the three sides.

How do you find the side length on a triangle with one angle given?
To find side lengths on a triangle, you need to know at least one of the sides. The possible combinations for solving* a triangle are: side, side, side; side, angle, side; angle, side, angle; angle, side, longer side. *To solve a triangle is to find the lengths of all the sides and the measures of all the angles.
A triangle with no sides of equal length?
a traingle can not have no sides, then it wouldnlt be a triangle, as far as i know, all 2d dimensional shapes have at least 3 SIDES, a shape with no sides isn't a shape, its nothing ness A scalene triangle- All sides are different
How do you find angles on a right triangle?
You do not need to, if you have a right triangle that angle is 90* so the other 2 angles are 45* apiece. That is actually only partially accurate. There can be a right angled triangle with sides of 2-3-5. 5 being the hypotenuse in which the triangle's angles will not be 90-45-45 but 90-33.69-56.31. To find the angles of a right triangle, you will need to know the length of the sides. With the length of all three sides, you will need to utilize sine, cosine, and tangent to find the angles.
How do you use pythagaoras theorem?
If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.If you know any two sides of a right triangle, you can calculate the third by Pythagoras' Theorem.
What can be found using the pythagorean theorem formula?
If you know two sides of a right triangle, the Pythagorean Formula lets you find the third side. Also, if you know all three sides of a triangle, you can confirm whether it is, or isn't, a right triangle.
How do you find the lengths of the sides of a triangle where one angle equals 90 degrees?
If you know the lengths of two sides then use Pythagoras' theorem to find the third side.
What is the formula for perimeter of a right triangle when one side is missing?
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
How do you find the perimeter of a scalene triangle when you only know two sides and the area?
To get the perimeter, you need to add all three sides. I assume you can get the third side by inserting the numbers you know into Heron's formula.
How do you find the pythagorean theorem of a triangle?
The Pythagorean theorem is a2 + b2 = c2. It is used for right triangles. If you know two of the sides, you can use the theorem to find the third side.
How do you find the two shorter sides of a triangle when all you know if the hypotenuse and nothing else?
If it has an hypotenuse then it is a right angle triangle and if you know its angles then use trigonometry to find its other two sides.
What is the difference between an scalene right triangle and a scalene obtuse triangle?
A scalene triangle is a triangle in which all three sides have different lengths. The difference between a scalene right triangle and a scalene obtuse triangle is that in the first one, we can find the measure length of the third side when we know the lengths of the two other sides, and in the second one we cannot.
How do you find the angles of an acute triangle?
Measure two of them. Then the third is 180 degrees minus the two that you know. Or measure the lengths of the sides and use the cosine rule.
What is the importance of phythagorean theorem in studying triangles?
If you know the length of 2 sides of a triangle, you can always find the length of the third using Pythag. Pretty neat!
How do you find the side length of a right triangle if you have one side length?
One side is not enough. For a right triangle the third side can be calculated by Pythagoras' Theorem if you know the length of any two sides.
How do you find the unknown length of a triangle?
If two sides are given and you need to know the length of the third side use the Pythagrean Theorem formula. Then you find the square root. c² = a² + b²* * * * *That is useful only if the triangle is a right angled triangle. Most are not. The correct answer depends on what information you do have.
