Properties of Congruent and Similar Shapes

1. Properties of Congruent and Similar Shapes

In this lesson, we'll look at triangles, rectangles and other shapes that share properties. This includes both congruent and similar shapes. We'll also practice identifying the missing properties of these shapes.

What is Translation in Math? - Definition, Examples, & Terms

2. What is Translation in Math? - Definition, Examples, & Terms

An object may be relocated in a coordinate plane by changing the coordinates of the points in an object while retaining the original shape of the object. Learn about the process of translation in mathematics and how it is done on geometric shapes and figures.

How to Identify Similar Triangles

3. How to Identify Similar Triangles

Similar triangles are defined as two triangles that possess proportional corresponding sides and congruent corresponding angles. Triangle similarity theorems use angle and side comparisons to determine whether two triangles are similar. Learn about the language of similarity, triangle similarity theorems (Angle-Angle, Side-Angle-Side, & Side-Side-Side), and how to use theorems to identify similar triangles.

Applying Scale Factors to Perimeter, Area, and Volume of Similar Figures

4. Applying Scale Factors to Perimeter, Area, and Volume of Similar Figures

How do shapes change sizes yet retain their proportions and similarities to other shapes? In this lesson, we'll look at what a scale factor is and how to apply it. We'll consider scale factors with regards to three different aspects of similar shapes: perimeter, area and volume.

Reflections in Math: Definition & Overview

5. Reflections in Math: Definition & Overview

When an object is reflected in math, it is flipped across a line. Explore the definition of reflections, what transformations are, how to draw reflections, and the overview of reflections in this lesson.

Rotations in Math: Definition & Overview

6. Rotations in Math: Definition & Overview

In mathematics, rotations occur when geometric figures move clockwise or counterclockwise around a specific point. Learn the definition and explore an overview of math rotations, which are one of four types of geometric transformations, including translation, reflection, and dilation.

Dilation in Math: Definition & Meaning

7. Dilation in Math: Definition & Meaning

Dilation in math is a transformation that changes the size of a figure so it becomes larger or smaller without changing shape. Study the definition of dilation and the meaning of dilations not on a coordinate plane and on a coordinate plane.
