Question

Below are three side lengths. Classify the triangle as acute, right, or obtuse, if possible. (Recall, that the sum of the two smaller sides must be greater than the third side to form a triangle). 20, 21, 29

Answer 1

Answer: Right Triangle

Step-by-step explanation: You can use the Pythagorean Theorem. a^2+b^2=c^2

You test if the equation is true. 21^2 x 20^2 = 29^2 which is 841 = 841
