Question 1064592: Can someone direct me please. Am I doing this correctly.
Draw a right triangle with the base of 2 units and a height of 3 units make three copies so that the length of the new sides are 50% , 300%, and 500% of the original.
My idea is
First triangle 2× 50 and 3× 50
Second triangle 2 × 300 and 3 ×300
Third triangle 2 × 500 and 3× 500

Question 1064603: I want to confirm if I understood .
Problem states : Draw a right triangle with a base of 2 units and a height of 3 units. Make three “copies” so that the lengths of
the new sides are 50%, 300%, and 500% of the original.
Solution:
1st triangle
Base2×0.5= 1 new base will be 2+1=3
Height 3×0.5=1.5 new height 3+1.5=4.5
So new triangle base 3units and height 4.5 units
Second triangle:
2×3=6 so, 6+2=8
3×3=9 so, 3+9=12
New triangle base 8 height 12

Question 1064724: I need help I'm not sure if I'm doing this right .
The shape is a trapezoid.
To see the image of shape it has the coordinates since I can upload the image but if you place it on graph paper.
(0,0), (0,6), (-3,6), (-9,0), (0,0)
I have to draw a smaller copy of it with sides 2/3 the length of the original.
So, I know 2/3 is 0.66
So do I subtract the sides from it can I get help at least one side
