write the to prove statement

If one angle of a triangle is 90°, then the other two add to 90°.

Step-by-step explanation:

Let one angle of a triangle is 90°.

Let in triangle ABC the measure of angle B is  90°.

According to the angle sum property of the triangle the sum of interior angles of a triangle is always 180°.

Using angle sum property of a triangle, we get,

Therefore the sum of angle A and C is 180°.

Hence proved that If one angle of a triangle is 90°, then the other two add to 90°.
