If m2 = 78°, then which other angles are also 78°? Select any angle that is congruent to 2. MCQ A. 1 B. 3 C. 4 D. 5 E. 6 F. 7 G. 8

Answer :

Final answer:

Angle 1 and angle 3 are congruent and have a measure of 78°. Congruent angles are angles that have the same measure.

Explanation:

Identifying congruent angles in a shape depends on the properties of the shape. For example, in a square, all angles are congruent because they all measure 90°. Conversely, in an isosceles triangle, only two angles are congruent. This concept can be applied to various shapes in geometry when you're trying to find congruent angles.

If m2 = 78°, then any angle that is congruent to 2 will also be 78°.

In a triangle, the angles add up to 180°, so if m2 = 78°, then m1 + m3 = 180° - 78° = 102°.

Therefore, angles 1 and 3 are congruent and also measure 78°.
