Question

Which statement is true?

Select one:
a. A ten degree angle is congruent to a 10 degree angle
b. A congruent angls is always 90 degrees
c. none of these
d. Congruent angles always add up to 90 degrees

Answer 1

For this problem, the answer is choice A.

Answer 2

The correct statement among the given statement is:

a. A ten degree angle is congruent to a 10 degree angle.

Explanation:

Congruent angles--

• Two angles are said to be congruent if both have the same angle measure.

• They may be of any measure.

• They may have any orientation on the plane.

Also, the construction of such a angle is simple with the help of a compass and a straight edge.

• Now, if we consider two angles such that the measure of each angle is 60 degree.

Then they add up to 60+60=120 degrees.

and hence options: b and d are incorrect.
