Perpendicular and Angle Bisectors

Front

What is the definition of perpendicular lines?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

What does it mean for two segments to be congruent?

Back

Two segments are congruent if they have the same length.

Front

What is an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

Front

If two triangles are congruent (∆ABC≅∆XYZ), what can we say about their corresponding sides?

Back

The corresponding sides of congruent triangles are equal in length.

Front

What is the relationship between a point and two figures if it is equidistant from both?

Back

The point is the same distance from both figures.

Front

How do you find the length of a missing side in a right triangle?

Back

Use the Pythagorean theorem: a² + b² = c², where c is the hypotenuse.

Front

What is the definition of equidistant?

Back

Equidistant means being the same distance from two or more points or figures.

Front

What type of angles are formed when two lines intersect?

Back

When two lines intersect, they form vertical angles that are congruent.

Front

What is the formula for finding the length of a side in similar triangles?

Back

The lengths of corresponding sides of similar triangles are proportional.

Front

What is the significance of the right angle in perpendicular lines?

Back

The right angle indicates that the lines meet at exactly 90 degrees, defining them as perpendicular.
