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:
- Equilateral triangle
- Isosceles triangle
- 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.
