  1. SHAPES and ANGLES DIFFERENT GEOMETRICAL SHAPES Triangle Rectangle

  2. Square Rectangle Oval ( ellipse ) Circle

  3. Angles Angles A ,B ,C are RIGHTANGLES Right Angle : An angle of measure 90 is called right angle. A B C Fig-1 Angles Q,R,S,T,U are obtuse angle Obtuse Angle : An angle of measure between 90 and 180 is called obtuse angle. R Q L P M U S O N Fig-2 T

  4. In fig-2 angles L,M,N,O,P are ACUTE ANGLES ACUTE ANGLES : An angle of measure < 90 is called acute angle Obtuse angle Acute angle Right angle

  6. 2ND

  7. EXERCISE -1 • Fill in the blanks…….. • A right angle is equal to ( 90° ) • An acute angle is less than ( 90° ) • An obtuse angle is more than(90°) and less than (180° ) • ⅟2 of a right angle is ( 45° ) • 2 right angle is (180° )

  8. EXERCIS-2 Draw angles of the following measures. and write their name. 45° B. 60° C. 90° D.120° Draw One acute angle , one obtuse angle and one right angle of any measure 3. Define acute angle ,obtuse angle and Right angle.

  9. Find : How many right angles are there in the given figure? Solution: The right angles in the given figure are: Thus, there are 14 right angles in the given figure.

  10. 2: Which angle is represented by the following figure? Solution: We know that in an acute angle, one arm is bent towards the other arm. Thus, the angle represented by the given figure is acute.
