Question 1.

circle

Answer:

A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.

Question 2.

Question 3.

Answer:

Circle: A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called the “centre”.

rectangle:

– It has four sides and four vertices

– Each vertex has an angle equal to 90 degrees

– The opposite sides are equal and parallel

square:

– All four interior angles are equal to 90°

– All four sides of the square are congruent or equal to each other

– The opposite sides of the square are parallel to each other

Right triangle: A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.

Question 4.

Answer:

rectangle:

– It has four sides and four vertices

– Each vertex has an angle equal to 90 degrees

– The opposite sides are equal and parallel

square:

– All four interior angles are equal to 90°

– All four sides of the square are congruent or equal to each other

– The opposite sides of the square are parallel to each other

**Directions: 1.** Draw circles and color them blue. **2.** Draw triangles and color them orange. **3-4.** Name the shape. Describe it. Compare the shape to each shape in the group. Circle the matching shapes.

Question 5.

Answer:

Circle: A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called the “centre”.

rectangle:

– It has four sides and four vertices

– Each vertex has an angle equal to 90 degrees

– The opposite sides are equal and parallel

square:

– All four interior angles are equal to 90°

– All four sides of the square are congruent or equal to each other

– The opposite sides of the square are parallel to each other

Triangle:

– It has 3 sides and 3 vertices.

Question 6.

Answer:

Hexagon: a hexagon is a closed two-dimensional six-sided polygon. It is made up of six line segments and six vertices that form six internal angles.

Regular hexagon: A hexagon is said to be a regular hexagon if the length of all the sides is equal and the measures of all the interior angles are the same.

Circle: A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called the “centre”.

Right triangle: A triangle in which one of the interior angles is 90° is called a right triangle. The longest side of the right triangle, which is also the side opposite the right angle, is the hypotenuse and the two arms of the right angle are the height and the base.

Question 7.

Answer:

The shape is a rectangle.

– It has four sides and four vertices

– Each vertex has an angle equal to 90 degrees

– The opposite sides are equal and parallel

Question 8.

Answer:

The shape is a square.

square:

– All four interior angles are equal to 90°

– All four sides of the square are congruent or equal to each other

– The opposite sides of the square are parallel to each other

**Directions: 5-6.** Name the shape. Describe it. Compare the shape to each shape in the group. Circle the matching shapes. **7-8.** Name the shape. Describe it. Compare the shape to each object in the group. Circle the objects that are the same shape.
