Answer:
A right angle has a value of 90 degrees (
90
∘
). A right triangle is a triangle in which one angle is a right angle. The relation between the sides and angles of a right triangle is the basis for trigonometry.
The side opposite the right angle is called the hypotenuse (side
c
in the figure). The sides adjacent to the right angle are called legs (sides
a
and
b
). Side
a
may be identified as the side adjacent to angle
B
and opposed to (or opposite) angle
A
. Side
b
is the side adjacent to angle
A
and opposed to angle
B
.Right triangle: The Pythagorean Theorem can be used to find the value of a missing side length in a right triangle.
Answer:
180°
Step-by-step explanation:
Right angle=90°
so,
2 right angle = 2×90°=180°
