If ABC is a right triangle and angle A=45°, what degrees are B and C?

WebAn acute angle has a measure, or it's smaller, than a right angle. When you learn about radians and degrees, which are different ways to measure angles, you'll see that a right angle can be measured as 90 degrees. This over here is less than 90 degrees. So this is less than 90 degrees. WebExplanation: Given that ∠A = 90°, ∠B = 45° By angle sum property of triangle, ∠A + ∠B + ∠C = 180° ⇒ ∠C = 45° Sides opposite to equal angles are equal. So, let AB = AC = x According … WebEither way, this angle and this angle are going to be congruent. So we've established that we have two triangles and two of the corresponding angles are the same. And that by itself is enough to establish similarity. We actually could show that this angle and this angle are also congruent by alternate interior angles, but we don't have to. job headhunters charlotte nc

WebIf this angle is 60 degrees, maybe this one right over here is 59 degrees. And then this angle right over here is 61 degrees. Notice they all add up to 180 degrees. This would be an acute triangle. Notice all of the angles are less than 90 degrees. A right triangle is a triangle that has one angle that is exactly 90 degrees.
