Given : ladder shaped shoe rack with four parallel racks

four cuboidal rods each of 120 cm long. Boards were placed at 20 cm, 45cm, 75cm and 110 cm from the top.

To Find :   Measure of angle x  

Which property can help him to check that all boards are parallel

Corresponding angle pairs are equal

Sum of corresponding angles must be 180°

Vertically opposite angles are equal

Sum of adjacent angles = 180°

Solution:

Properties of angles formed by transversal line  with two parallel lines :

• Corresponding angles are congruent.  

• Alternate angles are congruent.  ( Interiors & Exterior  both )  

• Interior angles are supplementary. ( adds up to 180°)

From given options

Corresponding angle pairs are equal

property can help him to check that all boards are parallel  

angle x is corresponding pair with 30°

measure of angle x = 30°
