How to see whether a triangle is right-angled or not |
|
Answer» -STEP explanation:A right triangle is a triangle in which one of the angles is a 90∘ angle. The "square" at the VERTEX of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the SIDE lengths are known. If the lengths satisfy the PYTHAGOREAN Theorem (a2+b2=c2) then it is a right triangle.フォローしてください最も簡単な回答としてマークします。 |
