Label the parts of the triangle.
leg
leg
altitude
hypotenuse
right angle

See Below

Step-by-step explanation:

One part we can label right off the bat is right angle. It is denoted with the red box. It forms a 90° angle, which is a right angle. At the very top pointing to the right angle, is right angle.

Altitude is another way of saying height. It is how tall the triangle is. The line that shows how tall the triangle is, is the line going down the triangle in the middle. That line is altitude.

Hypotenuse is the longest side of the triangle. It is also located directly across the right angle. Looking at the right angle, the bottom line is the hypotenuse.

Since we have 2 sides left, they are obviously the legs of the triangle.
