Match each shape to its name. (pp. 514, 520)

Question 1.  • The first and most important property of a regular hexagon is that it has six sides. Hexa means six and therefore a hexagon is supposed to have six sides.

• The next property is in continuation of the first property. As there are six sides, there are also six angles in a hexagon.

• The lengths of each side of a regular hexagon are equal.

• The angles of each side of a regular hexagon are equal.

Question 2.  Explanation:

• The sum of all the angles of a triangle (of all types) is equal to 180°.
• The sum of the length of the two sides of a triangle is greater than the length of the third side.
• In the same way, the difference between the two sides of a triangle is less than the length of the third side.
• The side opposite the greater angle is the longest side of all the three sides of a triangle.

Question 3.  Explanation:

• A rectangle is a quadrilateral
• The opposite sides are parallel and equal to each other
• Each interior angle is equal to 90 degrees
• The sum of all the interior angles is equal to 360 degrees
• The diagonals bisect each other
• Both the diagonals have the same length.

Question 4.  Explanation:

• Opposite angles are congruent or equal.
• The opposite sides are equal and parallel.
• Diagonals bisect each other.
• The Sum of any two adjacent or consecutive angles is 180°.
