The figure formed by joining the mid-point of the adjacent sides of a parallelogram is a rectangle (b) parallelogram (c) rhombus (d) square

Correct Answer - D The figures formed by joining the midpoints of the adjacent sides of different types of quadrilaterals are : `{:("Quadrilateral","Square","||gm","Rectangle","Rhombus"),(darr,darr,darr,darr,darr),("||gm","square","||gm","Rhombus","Rectangle"):}`

Two angles of a quadrilateral are 89° and 113°. If the other two angles are equal; find the equal angles.

Let the other angle = x° According to given, 89° + 113° + x° + x° = 360° 2x° = 360° – 202° 2x° = 158° x° = (158/2)°=79° ∴other two angles = 79° each
