a = 2b, so b = a/2; a = c - 10 so c = a + 10; a + b + c = 180.
a + a/2 + a + 10 =180, 2a + a + 2a = 360 - 20 ie 5a = 340
so a = 68, making b = 34 and c = 78.

Why cant you use angle angle angle to prove 2 traingles congruent?
Because if you take a triangle and double the length of each side, you get a much bigger triangle which is therefore not congruent (they do not match in every respect, even though the angles are replicated). In this case they are called "similar".
Why can a triangle have at most one right angle or one obtuse angle?
Because when you add up the measures of all 3 angles inside a triangle,they ALWAYS add up to exactly 180 degrees. In every triangle.-- If there were 2 right angles, then those two alone would add up to 180 degrees,even before you look at the third angle. Impossible.-- If there were two obtuse angles, then those two alone would add up to more than 180 degrees ...already impossible ... even without the third angle. Double impossible.
Do you double the area of a shape if it is a triangle?
No, you divide it by two.
How to form a double cone using a right-angled triangle?
u have to imagine it revolving... only this way it's possible to form a double cone with a right triangle.
What does a double line on all sides of a triangle mean?
It usually means that all sides are equal as in the form of an equilateral triangle.
What do you call polygons that have equal angles and proportional side lengths?
a double triangle
How do you find the diameter of a circle which would touch all three angles of an equalateral triangle?
Double its radius
Explain that the sum of interior angle is equal to quadrilateral 360?
Any quadrilateral may be split into two triangles; the sum of internal angles of any triangle is 180 degrees; so the sum of internal angles of a quadrilateral will then be the double of the sum of internal angles of a triangle: 180 x 2 = 360.
Double sheet measurement?
double the measurement of a single sheet.
What is the diameter of a exterior triangle in angles?
To work these things out,first you have to measure the outside of the triangle. your triangles may be different sizes but mine at school was 30 inches long which is large.Once you measured your triangle,work out how much angles the triangle could hold/fit.You have to have angles that are 10 inches long and another 10 inches high for the opening part.Now count how many angles you have.At school mine had 6 angles in the triangle.With the number of angles add double that number then see what number you get.For example,you had the number 10 so you double it which makes 20.So you have the starting number of your diameter which from instruction 4 is 20.Then using your number count how many times it can get to the number 100.For example,i had the number 20 so then i count it by 20's like this:20,40,60 and so on. I would end up with 5 turns with the number 20.then add 5 to the number you have and that's how much the diameter is of an exterior triangle in angles!so mine would be 25!Thankyou,i had fun explaining to you!see you next time!

What happens if you double the side lengths of a regular triangle?
You get a regular triangle whose sides are double the length.
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.
What does the double apostrophe symbol represent in measurement?
inches for length measurement, and seconds for angular measurement
Can there be a equilateral right triangle?
It is impossible for a right angled triangle to be equilateral unless it has a double triangle.

What conjectures in Classic or Euclidean Geometry have been proved from elementary axioms?
All the below listed conjectures (first letter C of Conjecture) can be proved using the Euclidean axioms of geometry. They can be used to teach or learn geometry. In this way one "discovers" the power of the Euglidean axioms.Some may be beyond this goal as they stand, as the definitions of key concepts is not included (e.g., centroid [C15], or "vertical" angle [C2], sometimes called a "right" angle.C1 Linear Pair: If two angles form a linear pair, then they are supplementary and total 180 degrees.C2 Vertical Angles: If two angles are vertical angles (right angles), then they are congruent.C3a Corresponding Angles: If two parallel lines are cut by a transversal, then the corresponding angles are congruent.C3b Alternate Interior Angles: If two parallel lines are cut by a transversal, then alternate interior angles are congruent.C3 Parallel Lines: If two parallel lines are cut by a transversal, then corresponding angles are congruent, alternate
