1/2 : 3/4 , 24 : 36 ... equivalent?

Step-by-step explanation:

find the product of means and product of extremes.If both are equal then it is equivalent.

Product of extremes=(1/2)*36 = 18

Product of means = (3/4)*24= 3*6 = 18

Product of extremes=Product of means

Therefore, 1/2 : 3/4 , 24 : 36  are equivalent

vertices are rotation by  270° about the origin

R¹( 3, 2), S¹( 2, -1) and T¹ (-1,- 2)

Step-by-step explanation:

Explanation:-

The rule for a rotation by 270° about the origin is

( x,y) → (y,-x)

Given vertices are  R(–2, 3), S(1, 2), and T(2, –1)

Given vertices are rotation by  270° about the origin

R¹( 3,-(-2)) , S¹( 2 , -1) and T¹ (-1 , -(2))

R¹( 3, 2), S¹( 2,-1) and T¹ (-1,- 2)
