Types of Triangles and Quadrilaterals

This page focuses on specific types of triangles and quadrilaterals, expanding on the properties of triangles and introducing various quadrilateral shapes.

The HL (Hypotenuse-Leg) congruence rule for right triangles is explained, which is a special case of triangle congruence.

Definition: The RHS congruence rule (also known as HL) states that if the hypotenuse and a leg of one right triangle are congruent to the corresponding parts of another right triangle, then the triangles are congruent.

Different types of triangles are defined, including right triangles, equilateral triangles, and isosceles triangles.

Vocabulary: An equilateral triangle has all sides equal, while an isosceles triangle has two equal sides.

The page then introduces various quadrilaterals: squares, rhombuses, rectangles, trapezoids, and parallelograms.

Example: A square is a quadrilateral with four equal sides and four right angles, combining properties of both rhombuses and rectangles.

Highlight: Understanding the properties of these shapes is crucial for solving problems in geometry worksheets and applying congruent triangles rules in more complex scenarios.

This comprehensive overview of triangles and quadrilaterals helps students build a strong foundation in geometry, preparing them for more advanced concepts in higher classes.
