HG Sections 4.1 - 4.3 Review 2

Front

What does it mean for two triangles to be congruent?

Back

Two triangles are congruent if they have the same size and shape, which means their corresponding sides and angles are equal.

Front

How can you determine the value of x in an equation involving angles?

Back

To determine the value of x in an equation involving angles, set the equation equal to the known angle measure and solve for x.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is a scalene triangle?

Back

A scalene triangle is a triangle in which all three sides are of different lengths and all three angles are of different measures.

Front

What is the relationship between corresponding angles in congruent triangles?

Back

In congruent triangles, corresponding angles are equal.

Front

How do you classify triangles based on their angles?

Back

Triangles can be classified as acute (all angles less than 90°), right (one angle equal to 90°), or obtuse (one angle greater than 90°).

Front

What is the formula for finding the measure of an angle in terms of x?

Back

The measure of an angle can be expressed as a linear equation in terms of x, such as m∠ = ax + b, where a and b are constants.

Front

What is the significance of the triangle congruence criteria (SSS, SAS, ASA, AAS, HL)?

Back

The triangle congruence criteria (Side-Side-Side, Side-Angle-Side, Angle-Side-Angle, Angle-Angle-Side, Hypotenuse-Leg) are used to determine if two triangles are congruent based on their sides and angles.

Front

How do you find the measure of an unknown angle in a triangle?

Back

To find the measure of an unknown angle in a triangle, subtract the sum of the known angles from 180 degrees.

Front

What is the definition of corresponding sides in triangles?

Back

Corresponding sides in triangles are the sides that are in the same relative position in two similar or congruent triangles.
