Are you searching for a way to teach your students how to identify and classify triangles and assess their knowledge? Use this PowerPoint presentation to teach classifying triangles by angles and sides. Then use the exit tickets as a follow up activity to see how well your students can classify triangles by angles and sides. Your students will learn the definitions of the different types of triangles - equilateral, isosceles, scalene, acute, obtuse, and right. Then students will show their understanding by identifying the different types of triangles.

Slides include:

• Review of the different types of triangles
• Examples of equilateral, isosceles, and scalene triangles
• Definitions of right, obtuse, and acute triangles
• Symmetry review
• Examples of symmetry in triangles

Exit Ticket Options:

Option 1 - Two on a page to save paper

Option 2 - Two on a page with word banks

Option 3 - Full page

Option 4 - Full page with word banks

Aligned with Common Core State Standards:

4.G.1: Draw points, lines, line segments, rays, angles (right, acute, obtuse), and perpendicular and parallel lines. Identify these in two-dimensional figures.

4.G.2: Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.

4.G.3: Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Identify line-symmetric figures and draw lines of symmetry.

5.G.3: Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category.

5.G.4: Classify two-dimensional figures in a hierarchy based on properties.
