Question

Triangle CRV has side lengths that measure 10 centimeters, 12 centimeters, and 15 centimeters. Which of the following best describes this type of triangle?

A) scalene triangle
b) equilateral triangle
c) isosceles triangle
d) obtuse triangle

Answer 1

A. Scalene, which just means three unequal sides.

Explanation:

An equilateral triangle has three equal sides and an isosceles triangle two, so it's not those.

Obtuse means there's at least one obtuse angle, always opposite the longest side. Here we have 10^2+12^2=244 which is greater than 15^2=225, indicating the angle opposite 15 is acute, so not this one either.

Answer 2

A) Scalene triangle.

Explanation:

We have been given that triangle CRV has side lengths that measure 10 centimeters, 12 centimeters, and 15 centimeters. We are asked to determine the type of triangle CRV.

We can see that the given measure of all sides are different. We know that a triangle is known a scalene triangle, when all its sides has different measures.

Since all the sides of triangle CRV has different measure, therefore, triangle CRV is a scalene triangle and option A is the correct choice.
