PRODUCT DESCRIPTION

Geometry Special Lines In Triangles Investigation Activity & Practice Worksheet

In this activity students discover the special lines in triangles and see how they impact the triangles.

The activity asks students to
1) Measure the side of a triangle and divide it in half to identify the midpoint.
2) Draw the three medians of a triangle by connecting the vertex to the midpoint of the opposite side in three types of triangles.
3) Draw the three altitudes of a triangle by connecting the vertex to the line containing the opposite side at a ninety degree angle in three types of triangles.
4) Draw the three perpendicular bisectors of a triangle by find the midpoint of a side and draw a line perpendicular to the side through that point in three types of triangles.
5) Identify the intersection point(s) between the three medians, the three altitudes and the three perpendicular bisectors of a triangle.
6) Draw conclusions about the three types of special lines in a triangle and determine their impact(s) on the triangles.

The one-page worksheet at the end asks students to apply the properties of these three special lines by solving practice problems.

I have also included a fully solved and illustrated teacher answer key for both the investigation and the worksheet at the end!

This is the perfect way to help students to truly see how the lines interact with triangle instead of just telling them!
