Geometry Chapter 4 Review part 1

Front

What does the SAS postulate state?

Back

The SAS (Side-Angle-Side) 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 two triangles are congruent.

Front

What does the SSS postulate state?

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 two triangles are congruent.

Front

What does the ASA postulate state?

Back

The ASA (Angle-Side-Angle) postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the two triangles are congruent.

Front

What does the AAS postulate state?

Back

The AAS (Angle-Angle-Side) postulate states that if two angles and a non-included side of one triangle are equal to two angles and the corresponding non-included side of another triangle, then the two triangles are congruent.

Front

What does the HL theorem state?

Back

The HL (Hypotenuse-Leg) theorem states that if the hypotenuse and one leg of a right triangle are equal to the hypotenuse and one leg of another right triangle, then the two triangles are congruent.

Front

How do you classify a triangle with all sides of different lengths?

Back

A triangle with all sides of different lengths is classified as a scalene triangle.

Front

How do you classify a triangle with two sides of equal length?

Back

A triangle with two sides of equal length is classified as an isosceles triangle.

Front

How do you classify a triangle with all sides of equal length?

Back

A triangle with all sides of equal length is classified as an equilateral triangle.

Front

What is the formula to find the perimeter of a triangle?

Back

The perimeter of a triangle is found by adding the lengths of all three sides: P = a + b + c.

Front

What is the formula to find the area of a triangle?

Back

The area of a triangle can be calculated using the formula: Area = 1/2 * base * height.
