"Understanding Isosceles Triangles and Equilateral Triangles" Triangles, Parallelograms and Trapezoid PPT Courseware

teaching objectives

1. Let students understand isosceles triangles and equilateral triangles and their characteristics in practical operations, know the names of the parts of an isosceles triangle, and be able to correctly judge whether a triangle is an isosceles triangle or an equilateral triangle.

2. Allow students to further develop their spatial concepts and cultivate their hands-on and thinking abilities in the activities of exploring graphic features and related conclusions.

3. Let students further develop curiosity about mathematics and increase their awareness of innovation during learning activities.

Give it a try

Take a square piece of paper and cut it diagonally. What triangles are the two triangles cut out?

Start drawing

Draw the other half of each figure below to make it an axially symmetrical figure, and talk about what triangles these axially symmetrical figures are.

Determine whether the following triangles are isosceles triangles.

1. The measures of the two angles are 70° and 40° respectively in a triangle.

2. There are two triangles with sides of 8 cm and 5 cm.

3. Use three small sticks of 22 cm, 10 cm, and 10 cm to surround it.
