Instructions for Use
Sorting Triangles allows students to identify and sort triangles by type.
To use Sorting Triangles, drag and drop each triangle in the correct location in the Venn diagram. Click the 'Next' button, to sort the triangles using different properties.
Identifying Triangles by Their Sides lets students select the type of triangle based on their sides.
To use Identifying Triangles by Their Sides, click the 'Start' button. Read the description of the side lengths, then and press the 'Equilateral', Isosceles', or 'Scalene' button. Feedback is provided for each answer submitted.
Identifying Types of Triangles by Angles lets students select the type of triangle based on the size of angles.
To use Identifying Types of Triangles by Angles, click the 'Start' button. Read the description of the angles sizes, and then press the 'Right', Obtuse', or 'Acute' button. Feedback is provided for each answer submitted.
Classifying Triangles lets students select a type of triangle based on its properties.
To use Classifying Triangles, click each type of triangle to identify its properties. Press the 'Click to Test Your Understanding' button. A triangle will appear with the size of angles and side lengths. Select the description for each triangle.
