#3 Is the triangle a right triangle? How do you know?

Answer:
the triangle is an isoceles triangle
Step-by-step explanation:
a triangle is equal in three sides
a isoceles triangle has three angle
Answer: definitely not, basically two of the sides have to be perpendicular to each other for it to be a right triangle. im pretty sure its an acute scalene triangle but i could be wrong
Step-by-step explanation: pythagorean theorem;
Step 1: A set of three distinct points (vertices) defines a triangle. Use the distance formula three times to find the distances between each pair of vertices. These are the lengths of the sides of the triangle.
Step 2: Let "c" stand for the longest side length. Let "a" and "b" stand for the shorter side lengths.
Step 3: Plug the values from Step 2 into a^2 + b^2 = c^2, to see if it holds true. If it holds true, the triangle is a right triangle according to the Pythagorean Theorem. Otherwise, the triangle is not a right triangle
