Question

Identify the triangle from the shapes given below.

• A. Shapes 1, 2, 3, and 4
• B. Only shape 1 and 4
• C. Only shape 2
• D. Only shapes 1, 3, and 4

Answer 1

The correct option is A Shapes 1, 2, 3, and 4

$\text{Say:}$Let’s read the question and observe the given images.

$\text{Ask:}$
$\bullet$ How can we identify a triangle?
Ans: We can identify a triangle by its 3 sides and 3 vertices.

$\bullet$ What is the shape of shape 1?
Ans: Triangle

$\bullet$ What is the shape of shape 2?
Ans: Triangle

$\bullet$ What is the shape of shape 3?
Ans: Triangle

$\bullet$ What is the shape of shape 4?
Ans: Triangle

$\text{Say:}$ Size and color are not the defining attributes of a shape. Therefore, though the shapes have different colors and sizes, they are all triangles because all 4 have 3 sides and 3 vertices, which are the defining attributes of a shape.

Hence, option D is the correct answer.

$\text{Probing Question:}$
Q. How are all the shapes similar to triangles, when they look so different?
A. A shape that is closed, and has 3 sides and 3 vertices is a triangle. All the three shapes are of different colors and different sizes but satisfy these 3 properties. So, they are all triangles.
