Lesson Worksheet: Types of Triangles: Sides Mathematics • 3rd Grade
In this worksheet, we will practice classifying triangles as equilateral, isosceles, or scalene by considering the lengths of their sides.
Q1:
What kind of triangles have all sides of the same length?
- Ascalene triangles
- Bequilateral triangles
- Cisosceles triangles
- Dright triangles
Q2:
What type of triangle is , in terms of its side lengths?
- Aisosceles triangle
- Bscalene triangle
- Cequilateral triangle
Q3:
Are the number of lines of symmetry of a scalene triangle less than, equal to or greater than the number of lines of symmetry of an isosceles triangle?
- AGreater than
- BEqual to
- CLess than
Q4:
Are the number of lines of symmetry of an isosceles triangles less than, equal to or greater than the number of lines of symmetry of an equilateral triangle?
- AEqual to
- BLess than
- CGreater than
Q6:
Complete the following: An equilateral triangle is a triangle whose sides are .
- Aintersecting at one point
- Bequal in length
- Cnot equal in length
- Dparallel
Q7:
Is an equilateral triangle an isosceles triangle?
- AYes
- BNo
Q8:
