Triangle abc is a right triangle. what is the relationship between angles a and b? they are congruent. they are complementary. they are supplementary.

A and B are complementary angles.

Step-by-step explanation:

We know that triangle ABC is a right angled triangle so one of the angles among A, B or C is 90°.

The sum of all three angles of a triangle is 180° so assuming angle C to be the right angle (i.e. 90°), we can write it as:

°

°

We know that if two angles add up to a sum of 90°, they are said to be complementary angles.

Since here in this case, , therefore A and B are complementary angles.

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.
