NCERT class 7 mathematics chapter 6 – “The Triangle and its Properties” teaches that the triangle is a simple closed curve made of three line segments. It has three vertices, three sides and three angles. For the CBSE exams, practice multiple-choice questions (MCQs) to prepare for the objective questions. We have provided Class 7 MCQ Questions on “The Triangle and its Properties” paired with comprehensive explanations. CBSE is emphasizing the role of MCQs as they assist in understanding the concepts completely.
As compared to subjective questions, MCQs are very different so practicing and understanding how to get appropriate answers in MCQs is very essential. To revise the main concepts, students should practice all the MCQs with the answers given. This will also help them familiarize themselves with the kinds of questions that might appear in the board exams.

Summary for NCERT class 7 mathematics chapter 6 – “The Triangle and its Properties”
- The six elements of a triangle are its three angles and the three sides.
- The line segment joining a vertex of a triangle to the mid point of its opposite side is called a median of the triangle. A triangle has 3 medians.
- The perpendicular line segment from a vertex of a triangle to its opposite side is called an altitude of the triangle. A triangle has 3 altitudes.
- An exterior angle of a triangle is formed, when a side of a triangle is produced. At each vertex, you have two ways of forming an exterior angle.
- The measure of any exterior angle of a triangle is equal to the sum of the measures of its interior opposite angles.
- The total measure of the three angles of a triangle is 180°.
- A triangle is said to be equilateral, if each one of its sides has the same length. In an equilateral triangle, each angle has measure 60°
- A triangle is said to be isosceles, if atleast any two of its sides are of same length. The non-equal side of an isosceles triangle is called its base; the base angles of an isosceles triangle have equal measure.
- The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
- The difference between the lengths of any two sides is smaller than the length of the third side.
- In a right angled triangle, the side opposite to the right angle is called the hypotenuse and the other two sides are called its legs.
- In a right-angled triangle, the square on the hypotenuse = the sum of the squares on its legs.
