Geometry: Understanding Triangle Angles

What is the relationship between mBC and mAD in a triangle?

Given mBC + mAD = 90°, what can we deduce from this information?

Answer:

The sum of angles mBC and mAD in the triangle is 90°.

In a triangle, the sum of all angles always adds up to 180 degrees. Therefore, if we are given that mBC + mAD = 90°, we can conclude that the two angles combined make up a right angle or 90 degrees in this particular triangle.
