## Build Two Congruent Triangles

I want you to build me two congruent triangles. Measure and label the side lengths using "units."

## Build Me Triangles with Constraints (Khan Academy)

1. Copy and paste this URL into a new window. Watch the video and do the practice.

## Build Me Three Unique Triangles

1. None of the triangles should be congruent.
2. You should build one of each type. If you need to review types watch video to help!
3. Use this video to help if needed! https://www.youtube.com/watch?v=JQUTVgT9RXY
4. Classify each triangle based on their side lengths.

## Study Images of Transformations (You will practice these next!)

## Translation

Build a square and translate it three units right and four units down.

## Rotation

Build a triangle and rotate it 180 degrees clockwise.

## Reflection

Build any quadrilateral and reflect it across the x-axis and then reflect again across the y-axis.

## Enlargement

Build any triangle and enlarge it by a scale factor of two.
