Q3: Identify the following triangles according to the measurement of sides and angles given. Also mention the type of triangle:

(e.g. (1) ∆ABC is an equilateral triangle and acute angled triangle.
Ans: (1) ∆ABC: Equilateral and acute angled triangle
(2) ∆DEF: Isosceles triangle and acute angled triangle
(3) ∆GIH: Scalene triangle and right angled triangle
(4) ∆JKL: Isosceles triangle and obtuse angled triangle
(5) ∆MNO: Scalene triangle and obtuse angled triangle
(6) ∆PQR: Scalene triangle and acute angled triangle
(7) ∆STV: Isosceles triangle and right angled triangle

Q4: Match the column B with A and C:

 A B C (a) Straight angle (i) An angle whose measure is less than 90°. (f) One fourth of a revolution. (b) Right angle (ii) An angle whose measure is between 90° and 180°. (g) Half of a revolution. (c) Acute angle (iii) An angle whose measure is 180°. (h) More than half a revolution (d) Obtuse angle (iv) An angle whose measure is 90°. (i) Less than one-fourth of a revolution. (e) Reflex angle (v) An angle whose measure is between 180° and 360°. (j) Between ¼ and ½ of a revolution.

For example (a) → (iii) → (g)
Ans: (a) → (iii) → (g)
(b) → (iv) →  (f)
(c) → (i) →  (i)
(d) → (ii) →  (j)
(e) → (v) →  (h)

## FAQs on Understanding Elementary Shapes Class 6 Worksheet Maths Chapter 5

 1. What are the different types of elementary shapes?
Ans. The different types of elementary shapes include squares, rectangles, circles, triangles, and hexagons. These shapes are the basic building blocks for more complex figures.
 2. How do you identify a square?
Ans. A square is a four-sided polygon with all sides equal in length and all angles equal to 90 degrees. To identify a square, we can measure the length of its sides and check if all sides are equal and if all angles are right angles.
 3. What is the formula to calculate the area of a circle?
Ans. The formula to calculate the area of a circle is A = πr^2, where A represents the area and r represents the radius of the circle. The value of π is approximately 3.14.
 4. How many sides does a hexagon have?
Ans. A hexagon has six sides. It is a polygon with six straight sides and six angles.
 5. How do you find the perimeter of a triangle?
Ans. To find the perimeter of a triangle, you need to add the lengths of all three sides. If the lengths of the sides of the triangle are given, simply add them together to get the perimeter.
