The measure of an exterior angle of a right triangle is 135 degrees. find the measures of the interior angles of the triangle.

The measure of the interior angles of the right triangle are 90 degrees, 67.5 degrees, and 67.5 degrees. The exterior angle of a triangle can be found by the sum of the opposite angles in the triangle so 135/2 = the angles you need and 67.5 + 67.5 + 90 = 180.

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
