Question

Question 1:
Which of the followings (not drawn to scale) are right-
angled triangles?
12cm. 5cm and. 13cm​

Answer 1

Answer:

Step-by-step explanation:

by applying Pythagoras theorem

(13)^2= (5)^2+(12)^2----------------equation 1

( here we have taken 13cm as the hypotenuse because in a triangle side opposite to tha largest angle is the largest side of that triangle)

from equation 1

169=169

hence it is following the Pythagoras theorem so it's a right angled triangle

Answer 2

Yes ..it is possible with Henry's formula nd sin formula
