Question

Suppose you have triangle ABC and triangle DEF, and they are similar, with a scale factor of 0.5. If the angle measures of ABC are 80°, 80°, 20°, what are the measures of the angles in DEF?

40°, 40°, and 10°
40°, 40°, and 100°
80°, 80°, and 20°
Cannot be determined.

Answer 2

Hello;

Since both triangle are similar they both have same angles.

Hence angle measure of DEF are

80°, 80°, and 20°

Hope this has helped you, good luck!
