Answer:
Sure, I'd be happy to help! Here's the diagram you provided:
The angle labeled as "180°" in the diagram is actually 90°, not 180°.
Here's why:
1. The angle at the top of the triangle, labeled as "A," is 90°. This is because the angle at the top of an isosceles triangle is always 90°.
2. The angle at the bottom of the triangle, labeled as "B," is also 90°. This is because the two sides of an isosceles triangle are of equal length, and the angle between them is also equal.
3. The angle labeled as "C" is 180° - 90° = 90°. This is because the sum of the interior angles of a triangle is always 180°, and we have already accounted for 90° of those angles with angles A and B.
So, to summarize:
The angle labeled as "180°" in the diagram is actually 90°.
