Question

Concept Check Classify each triangle as acute, right, or obtuse. Also classify each as equilateral, isosceles, or scalene. See the discussion following Example 2.

Accepted Answer

Hello, today we're going to be determining whether the given triangle is right acute or obtuse. And we'll also be categorizing the triangle as equilateral isosceles or scale. So we are given a triangle A B and C. Let's go ahead and start by categorizing it as a cute right or obtuse. Now, if we took a look at angle C of the triangle angle C has the square marking for the, for the angle, this square marking indicates that this angle has a measure of degrees. And whenever a triangle has a measure of 90 degrees, any angle that is equal to 90 degrees indicates that the triangle is going to be a right triangle. So we can categorize this triangle as a right triangle. Now, let's move on to categorizing it as equilateral isosceles or Sica. Now, if we take a look at the side links AC and the side length BC, one thing to note is that both of these lengths are equal to 13. Since both of these links have the same measurement of 13, this indicates that the triangle has two equivalent sides. The definition for an Isosceles triangle is any triangle with two equivalent sites. And since this triangle has two equivalent sides, we can identify the triangle as an isosceles triangle. So now that we know that the triangle is a right triangle and an isosceles triangle, the answer to this problem is going to be B so I hope this video helps you in understanding how to determine how to understand this problem. And I'll go ahead and see you all in the next video.
