Are the rectangles with dimensions
2×5 and 12×9 2 \times 5 \text{ and } 12 \times 9 2×5 and 12×9
similar?
Quadrilaterals ABCDABCDABCD and EFGHEFGHEFGH satisfy AB=2EF,BC=2FG,CD=2GH,DA=2HE AB = 2EF, BC = 2FG, CD =2GH, DA = 2HE AB=2EF,BC=2FG,CD=2GH,DA=2HE.
Must they be similar?
8×5 and 25×40 8 \times 5 \text{ and } 25 \times 40 8×5 and 25×40
Are the parallelograms with side lengths
4×15 and 60×16 4 \times 15 \text{ and } 60 \times 16 4×15 and 60×16
Consider parallelograms ABCD ABCDABCD and EFGH EFGH EFGH. We know that AB=2,BC=9,EF=4,FG=18 AB = 2, BC = 9, EF = 4, FG = 18 AB=2,BC=9,EF=4,FG=18, ∠ABC=40∘ \angle ABC = 40^\circ ∠ABC=40∘ and ∠EFG=140∘ \angle EFG = 140^ \circ ∠EFG=140∘.
Are these parallelograms similar?
