Gr8 - Similar Figures, Translation and Reflection

Front

What are similar figures?

Back

Similar figures are shapes that have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape. Common transformations include translation, reflection, rotation, and enlargement.

Front

What is translation in geometry?

Back

Translation is a type of transformation that slides a figure from one position to another without turning it. The shape and size remain the same.

Front

What is reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image of the original figure.

Front

What is the X-axis?

Back

The X-axis is the horizontal line in a coordinate plane where the y-coordinate is zero. It is used to measure the horizontal position of points.

Front

What is the Y-axis?

Back

The Y-axis is the vertical line in a coordinate plane where the x-coordinate is zero. It is used to measure the vertical position of points.

Front

If two triangles are similar, what can we say about their angles?

Back

If two triangles are similar, their corresponding angles are equal.

Front

What is the sum of the angles in any triangle?

Back

The sum of the angles in any triangle is always 180 degrees.

Front

How do you find the corresponding side in similar triangles?

Back

To find the corresponding side in similar triangles, use the ratio of the lengths of the sides of the triangles.
