The properties of a Rectangle 4 Right Angles 1. All the angles are 90° 2. The opposite sides are parallel and equal.

The Properties of a Square . 4 Right Angles 1. All 4 angles of a square are right angles. 2. The opposite sides of a square are equal 3. The opposite sides of a square are parallel.

Page 99. Exercise 6.1 Look at the figures below : Fill in the boxes with the correct answers. 1. PQ = PS = RS = QR PQ // RS , PS // QR All the angles are right angles PQRS is a Square.

ST = VU , TU = SV ST // VU , SV // TU All the angles are right angles. STUV is a Rectangle

3. A square has 4 sides and 4 vertices. 4 3. A square has 4 sides and 4 vertices. 4. A rectangle has 4 sides and 4 vertices. A rectangle has 4 right angles.

Pages 100 B. Find the length of the unknown sides. LMNO is a square. LO = 8 cm. LM = 8 cm. MN = 8 cm.

PQRS is a rectangle. Its length is twice its breadth. QR = 16 cm. PS = 16 cm.

STUV is a square. SV = 25 cm. ST = 25 cm TU = 25 cm.

ABCD is a rectangle. AB = 5 cm. AD = 8 cm.

Page 101 Exercise 6.2 Find the unknown marked angles in the squares and rectangles. 1. PQRS is a square. Find b 90° - 55° = 35° Answer : 35°

2. ABCD is a rectangle. Find x 90° - 58° = 32° Answer : 32°

LMNO is a rectangle. Find Y 90 ° - 46 ° = 44 ° Answer : 44 °

Page. 102 ABCD is a square. Find x 90° - 30° - 20 ° = 40° Answer : 40°

5. EFGH is a rectangle. Find z 90° - 28° - 20 ° = 42° Answer : 42°

6. WXYZ is a rectangle. Find b 90° - 28° - 36 ° = 26° Answer : 26°

Page 103 : Exercise 6.3 A. Find the length of the stated sides in each figure. 1. This figure consists of a rectangle and a square. Find DE and BF. DE = DC – CE BF = BC – FC = 10 – 4 = 10 – 4 = 6 cm. Ans. = 6 cm. Ans.

2. The figure has a rectangle and a square. Find UR 2. The figure has a rectangle and a square. Find UR. UR = QR - QT - VW = 16 - 6 - 5 = 5 cm. Ans.

3. The figure consists od the two rectangle. Find MR and NO 3. The figure consists od the two rectangle. Find MR and NO. MR = OR - OM NO = NM - OM = 10 – 7 = 12 - 7 = 3 cm. Ans. = 5 cm. Ans.
