Triangles measure 180 degrees. A triangle that has one 90 degree angle is known as a right triangle.
The other two angles each measure 90 degrees
A right angle measures 90 degrees
A right angle is a 90 degree angle.
It is a right angle triangle and angle A measures 15 degrees.

The corner of a square measures 90 degrees which is a right angle.
90 degrees
In a right triangle, the sum of the angles is always 180 degrees, with one angle measuring 90 degrees. Therefore, the measures of the other two angles, including angle ABC, must add up to 90 degrees. To find the measure of angle ABC, you would need the measure of the other non-right angle in the triangle. If, for example, angle BAC is known to be 30 degrees, then angle ABC would measure 60 degrees.
Triangles measure 180 degrees. A triangle that has one 90 degree angle is known as a right triangle.
Two angles that measure up to 90 degrees are called complementary angles. For example, a 30-degree angle and a 60-degree angle are complementary because their sum is 90 degrees. Another example is a 45-degree angle and a 45-degree angle, which also add up to 90 degrees.
The other two angles each measure 90 degrees
A right angle measures 90 degrees. One sixth of a right angle is calculated by dividing 90 degrees by 6, which equals 15 degrees. Therefore, the degree measure of one sixth of a right angle is 15 degrees.
A right angle measures 90 degrees
Using a protractor which should give a measure of a 90 degree angle and two acute angles that add up to 90 degrees.
A right angle is a 90 degree angle.
It is a right angle triangle and angle A measures 15 degrees.
