Question

Triangle was rotated 90° counterclockwise about point P to create DEF as shown.

Which angle ash has a measure of 62°

A,<EJK
B,<FDE
C,<FED
D,<BAC
​

Answer 1

The angle that has a measure of 62° is FED. Option C

To determine the angle, we have to know the following;

• Adjacent angles are equal
• Congruent angles are equal
• The sum of angles on a straight line is 180 degrees
• Vertically opposite angles are equal
• Corresponding angles are equal

From the diagram shown, we can see that the angle FED is same-side interior angle with angke CBA

Thus, angle FED is 62 degrees
