(Q1)an acute triangle is (sometimes, always, never) similar to and obtuse triangle. (Q2 ) 2 rectangles are (sometimes, always, never) similar.

Answer 1

(Q1) An acute triangle is (sometimes, always, never) similar to and obtuse triangle.

This is because an acute triangle’s internal angles are all acute (< 90º). An obtuse triangle has an obtuse angle (> 90º).

(Q2) Two rectangles are (sometimes, always, never) similar.

Even though every angle in any rectangle is always 90º, rectangles are only similar if their sides are in the same proportion.

Answer 2

What; are the conditions for two figures to be similar?
