### 1. Types of Angles: Vertical, Corresponding, Alternate Interior & Others

Understanding angles and angle relationships allows for easier calculation of angle measurement. Learn how to define various types of angles, including vertical, corresponding, alternate interior angles, and how to calculate degree measurement using angle relationships.

### 2. Vertical Angles & Complementary Angles: Definition & Examples

Vertical angles and complementary angles can be used to calculate unknown angle measurements. Learn the definition of vertical angles and review examples of how to use the properties of vertical angles and complementary angles to find the missing angle's measurements.

### 3. Triangles: Definition and Properties

Triangles are shapes with three sides and three angles that lie on a two dimensional plane. Study the definition and properties of triangles including sides and angles, base and height, and opposite and adjacent sides.

### 4. Classifying Triangles by Angles and Sides

Triangles are two-dimensional shapes that have three sides, which can be a variety of lengths to create three angles of varied sizes. Learn how to classify triangles on the basis of their angles and sides, and explore the properties of scalene, isosceles, equilateral, acute, obtuse, and right triangles.

### 5. Properties of Shapes: Quadrilaterals, Parallelograms, Trapezoids, Polygons

There are many different properties of shapes, but the perimeter of all of them is the sum of all its sides. Explore the properties of the more complicated shapes, including quadrilaterals, parallelograms, trapezoids, and polygons.

### 6. How to Read and Interpret Scale Drawings

A scale drawing depicts an actual object with its size reduced or enlarged proportionately according to a scaled amount. Learn how to read and interpret scale drawings. Explore legends, reading a map, and reading a model drawing to understand how to use scale drawings to understand objects that are difficult to comprehend in their actual size.
