1.	The lengths of the sides of some triangle aregiven below find out which of them are right. angled triangle4.5cm, 6cm,7.5 cm
Answer» Step-by-step explanation: Draw a line, AB, 7.5 CM. With A as center and a RADIUS of 4.5 cm draw an arc. With B as center and a radius of 6 cm draw an arc to cut the previous arc at C. Join AB, BC and CA. ABC is the DESIRED triangle. Check that AB^2 =BC^2+CA^2. 7.5^2 = 4.5^2+6^2 56.25 = 20.25 + 36 = 56.25. Therefore

Step-by-step explanation:

Draw a line, AB, 7.5 CM. With A as center and a RADIUS of 4.5 cm draw an arc.

With B as center and a radius of 6 cm draw an arc to cut the previous arc at C. Join AB, BC and CA.

ABC is the DESIRED triangle. Check that

AB^2 =BC^2+CA^2.

7.5^2 = 4.5^2+6^2

56.25 = 20.25 + 36 = 56.25.

Therefore
