Geometry ACT Math Prep: Area of Compound Figures

Posted on by Nathaniel

In this ACT Math video, we delve into Geometry and cover compound figures, which are also called composite figures. Compound figures are figures that when cut are made up of common shapes such as squares, rectangles, circles, triangles and trapezoids.

When the ACT test gives problems like this, you will usually need to find unknown sides of the figure before you can proceed to find the area. For this ACT Math example, we find missing sides of the compound figure, and then show four different ways to get the area.

The example used in the video will be based off the following ACT math problem below:

This is the practice exercise we will work out in the video:

This practice problem is considered a MEDIUM difficulty problem.

Geometry ACT Math Prep: Midpoints and Endpoints

Posted on by Nathaniel

In this ACT Math prep video, we cover a classic ACT math problem that shows up all the time on the ACT. You are given the midpoint and one of the endpoints of a segment, and you must find the coordinates of the other endpoint of the segment.

This problem continues to show up on the ACT, mainly because students continue to get it incorrect. In the video, we show three different methods for using the given midpoint to find the missing endpoint.

The example used in the video will be based off the following ACT math problem below:

Sometimes we may need to figure out the areas of several shapes to solve an ACT math problem. We can use basic shapes like rectangles and triangles to find the area of less common figures such as pentagons and hexagons.
