Question

Construct the AABC, with angle B =90°, AB = 4 cm & AC = 5 cm and measure

the third side​

Answer 1

Answer:3rd side is 3 Cm

Step-by-step explanation:

ac is the hypotenuse as it is opposite to b=90 degrees so use pythagoras theorem ac sqaure=ab sqaure + bc square which is equal to 25=16+9 you get 9 by subtracting 16 from 25 and then root of 9 is 3 so viola

Answer 2

Steps of construction:

• Draw a line segment XY.
• Locate A, B on XY such that AB = 4cm
• Construct a line segment BD, sufficiently large, such that ∠B = 90°
• With A as centre and radius 5cm draw an arc, cutting BD at A; join AC.
• Then, ABC is the required triangle.
