1st Semester Exam Review 24-25

Front

What are alternate interior angles?

Back

Alternate interior angles are pairs of angles that are on opposite sides of a transversal and inside two parallel lines. They are equal in measure.

Front

Which postulate states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent?

Back

SAS (Side-Angle-Side) Postulate.

Front

What are corresponding angles?

Back

Corresponding angles are pairs of angles that are in the same position on two parallel lines cut by a transversal. They are equal in measure.

Front

Which postulate states that if two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent?

Back

AAS (Angle-Angle-Side) Postulate.

Front

What does the notation ∆ABC≅∆XYZ signify?

Back

It signifies that triangle ABC is congruent to triangle XYZ, meaning all corresponding sides and angles are equal.

Front

What is the SSS postulate?

Back

The SSS (Side-Side-Side) Postulate states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the difference between acute, obtuse, and right angles?

Back

Acute angles measure less than 90 degrees, obtuse angles measure more than 90 degrees but less than 180 degrees, and right angles measure exactly 90 degrees.

Front

How do you identify vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always equal.

Front

What is the definition of a transversal?

Back

A transversal is a line that intersects two or more lines at different points.

Front

What is the relationship between the angles formed by a transversal and parallel lines?

Back

When a transversal intersects parallel lines, several pairs of angles are formed, including alternate interior angles, corresponding angles, and same-side interior angles, which have specific relationships (e.g., alternate interior angles are equal).
