Question

Which triangle is a 30°-60°-90° triangle?

Answer 1

Hopefully, you remember that the hypotenuse in a right triangle is the longest side, which is also directly across from the 90 degree angle. It turns out that in a 30-60-90 triangle, you can find the measure of any of the three sides, simply by knowing the measure of at least one side in the triangle.

Answer 2

Scalene triangle

Explanation:

A scalene triangle is a triangle in which the three sides have different lengths. Also the angles of a scalene triangle have different measures. For example, given a triangle which sides are a,b,c and its angles are α, β, γ then:

`a\\eq b \hspace{3},\hspace{3} a\\eq c \hspace{3},\hspace{3}b\\eq c\\\alpha\\eq \beta\hspace{3},\hspace{3} \alpha\\eq \gamma\hspace{3},\hspace{3}\beta\\eq \gamma`
