Respuesta :

Right and scalene. A right triangle has an angle that measures to be 90° and using the pythagorean theorem, we know that the triangle is scalene, meaning that all three sides have different side lengths. (:

3² + 4² = 5²

A triangle has an angle that measures 90° is a right angle triangle that is option D is correct.

What is a Triangle?

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

Types of the triangle are as follows:

  1. Equilateral triangle
  2. Isosceles triangle
  3. Right-angle triangle

1. Equilateral triangle

It is the triangle in which all three sides are equal. And each angle is 60°.

2.  Isosceles triangle

It is a triangle in which two sides are equal.

3.  Right angle triangle

It is a type of triangle in which one angle is 90° and it follows the Pythagoras theorem and we can use the trigonometry function.
