Triangle unit test seventh grade

Answer 1

Here is a possible unit test for seventh grade students on triangles:

1. Define the following terms: equilateral triangle, isosceles triangle, scalene triangle.
2. Identify whether each triangle is equilateral, isosceles, or scalene:
a) Triangle ABC with side lengths of 5 cm, 5 cm, 5 cm
b) Triangle DEF with side lengths of 4 cm, 4 cm, 6 cm
c) Triangle GHI with side lengths of 3 cm, 4 cm, 5 cm
3. Calculate the perimeter of Triangle JKL with side lengths of 12 cm, 15 cm, 17 cm.
4. Find the missing angle in Triangle MNO if angle M = 50° and angle N = 70°.
5. Determine if the following statement is true or false: In a right triangle, the length of the hypotenuse is always equal to the sum of the lengths of the other two sides.
6. If Triangle PQR is similar to Triangle STU with a scale factor of 2, and the length of side PQ is 8 cm, what is the length of side ST?

These questions cover a range of topics related to triangles, including types of triangles, perimeter, angles, similarity, and the Pythagorean Theorem. Students can be assessed on their knowledge and understanding of these concepts through this unit test.
