Question

question 3 of 10 is the following shape a right triangle? how do you know? a. yes, two sides are perpendicular, and the side lengths fit the pythagorean theorem. b. no, there is no right angle. c. no, the side lengths do not fit the pythagorean theorem. d. there is not enough information to determine.

Explanation:

Step1: Check for right - angle

Visually or by slope calculation, if two sides are perpendicular, a right - angle exists.

Step2: Apply Pythagorean theorem

For a right - triangle with side lengths \(a\), \(b\), and hypotenuse \(c\), \(a^{2}+b^{2}=c^{2}\). If side lengths satisfy this, it's a right - triangle.

Answer:

A. Yes, two sides are perpendicular, and the side lengths fit the Pythagorean theorem.
