4. A triangle has a 90° angle and two sides that measure 5 cm in length. Which statements are true about this triangle? Select all that apply. A. The triangle must be an isosceles triangle. B. The triangle must be an equilateral triangle. C. The triangle must be a right triangle. D. The triangle must be an acute triangle. E. The triangle must contain an angle measuring 45° F. The third side of the triangle might be 10 cm in length.​

Respuesta :

The triangle is an isosceles right triangle, and the true statements about the triangle are

  • The triangle must be an isosceles triangle.
  • The triangle must be a right triangle.
  • The triangle must contain an angle measuring 45°

How to determine the true statements?

The given parameters are:

Angle = 90 degrees

Two side lengths = 5 cm

Given that one of the angles is 90 degrees, then it means that the triangle is a right triangle.

Also since two sides are equal, then the triangle is an isosceles triangle, and the other angles are 45 degrees each

Hence, the true statements about the triangle are (a), (c) and (e)
