Overview

Students will be able to identify the various types of angles and triangles, explain their attributes and identify these angles and shapes in real life pictures and situations.

Standards

Mathematics
Measurement and Geometry
2.0 Students describe and compare the attributes of plane and solid geometric figures and use their understanding to show relationships and solve problems.
2.2 Identify attributes of triangles (e.g., two equal sides for the isosceles triangle, three equal sides for the equilateral triangle, right angle for the right triangle).
2.4 Identify right angles in geometric figures or in appropriate objects and determine whether other angles are greater or less than a right angle.

National Educational Technology Standards for Students (NETS)

1.0 Creativity and Innovation

Students demonstrate creative thinking, construct knowledge, and develop innovative products and processes using technology.

1.c Students use models and simulations to explore complex systems and issues.

Essential Questions
How are angles and triangles related?

Activities

Students will create a "Triangle Trees" picture. They will draw four different triangle "tree tops", using their rulers to measure and draw the triangles to include a right triangle, an isosceles triangle, a scalene triangle and an equilateral triangle. Each "triangle tree" will be labeled with the correct triangle name. Students will add details (tree trunks, sky, and ground) to complete their picture. Note: See uploaded file section for an example of the picture.
Working with a partner, students will go on a "webquest" for pictures that demonstrate each of the following triangles and angles: right, scalene, isosceles, equilateral, acute, and obtuse. Each group will "cut and paste" each picture onto a new document and label each triangle picture.

E xtension Activities

Students will investigate the origin of the names of the isosceles and scalene triangles. They will write a one-paragraph report on how these type of triangles got their names.
