Another engineer is tiling a new building. A square tile is cut along one of its diagonals to form two triangles with two congruent angles. What are the measurements of the interior angles of the triangles? Explain how you calculated them.
Answer
Answer:
The interior angles are 90°, 45°, and 45°. The triangle has a right angle because it shares an angle with the square. The equation 90 + 2x = 180 can be used to find the two congruent angles.
