Right Triangle Geometry: Finding the Sum of Non-Right Angles

Question

In a right triangle, the sum of the two non-right angles is...?

Video Solution

Solution Steps

00:04 Let's find the sum of the non-right angles in a right triangle.
00:09 Label these angles as A and B.
00:16 Remember, the sum of all angles in a triangle is 180 degrees.
00:21 In a right triangle, one angle is 90 degrees, so A plus B equals 90 degrees.
00:34 And that's how you find their sum!

Step-by-Step Solution

In a right-angled triangle, there is one angle that equals 90 degrees, and the other two angles sum up to 180 degrees (sum of angles in a triangle)

Therefore, the sum of the two non-right angles is 90 degrees

90+90=180 90+90=180

Answer

90 degrees
