Every triangle has three angles, and these three angles will always add up to 180 degrees. We can prove this with the use of parallel lines or by cutting off the angles and lining them up to see that they form a
When we look at the three angles underneath Line 1, we can see that they add up to 180 degrees just as we know they must. And the three angles in the triangle have the same three angle measures. This will always be true. If we rotate the line we added and look at the measures ag...

Like all triangles, the angle values of a right angled triangle add up to a sum of 180 degrees. This also means that the two non-right angles of the triangle must add up to 90 degrees. Solving a Right Angled Triangle Using Pythagorean Formula ...

Do isosceles triangles add up to 180? All triangles have interior angles that add up to 180 degrees. An isosceles triangle has two angles that must be equal to each other and less than 90 degrees. How do you find the third side of an isosceles triangle? Finding the third side of an is...
For instance, a triangle has three interior angles and a hexagon has six interior angles. How do you find the exterior angle? Adjacent exterior and interior angles always add up to 180 degrees (i.e. are supplementary angles). That means you can find the exterior angle by subtracting the ...
