Question

A right triangle has a line of symmetry select all conclusions that must be true

Answer 1

Where are the choices?

a rigth triangle is a 90 degree angle.

In geometry and trigonometry, a right angle is an angle of exactly 90°, corresponding to a quarter turn. If a ray is placed so that its endpoint is on a line and the adjacent angles are equal, then they are right angles.-wikipedia

no one can report because I gave wikipedia credit

Explanation:

your welcome:)

Answer 2

The correct conclusions are:

c. Two sides of the triangle have the same length.

d. Two angles of the triangle have the same measure.

How to determine the conclusions that must be true

From the question, we have the following parameters that can be used in our computation:

A right triangle has a line of symmetry

A right triangle can have a line of symmetry, but it does not imply that all sides or angles are necessarily equal.

A line of symmetry would mean that the triangle is isosceles, having at least two sides of equal length and two angles of equal measure

This specifically means that the angles opposite the equal sides
