Question

labeling sides of right triangles
right triangles have one ______ ° angle, and the side opposite that angle is called the
___________. the other legs of the triangle can be considered opposite sides or
_________ sides, depending on what angle you want to consider.
consider ∠a
consider ∠b

Explanation:

Step1: Recall right triangle properties

A right triangle has one \( 90^\circ \) (right) angle. The side opposite the right angle is the hypotenuse. The other two sides (legs) can be called opposite or adjacent relative to an acute angle.

Step2: Fill in the blanks

1. Right triangles have one \( \boldsymbol{90}^\circ \) angle.
2. The side opposite the right angle is the \( \boldsymbol{\text{hypotenuse}} \).
3. The other legs are opposite or \( \boldsymbol{\text{adjacent}} \) sides (relative to an acute angle).
4. For \( \angle A \), side \( AC \) (adjacent to \( \angle A \)) is labeled as \( \boldsymbol{\text{Adjacent}} \).
5. For \( \angle B \), side \( AC \) (opposite to \( \angle B \)) is labeled as \( \boldsymbol{\text{Opposite}} \).

Answer:

First blank: \( 90 \)
Second blank: hypotenuse
Third blank: adjacent
Fourth (under \( \angle A \)): Adjacent
Fifth (under \( \angle B \)): Opposite
