How many Triangles are needed to make a star when we connect them with their smaller acute angle​

I think it's 5 triangle are needed to make star

The answer depends on how you count them; for example, are you allowed to count the same line segment multiple times to make multiple triangles out of the same segment, or must each line segment appear in only one triangle in your count?

Step-by-step explanation:

To draw a Jewish star, you really draw only two large triangles: one pointing up and the other pointing down. However, the overlap of these two triangles forms six additional smaller triangles at each tip in addition to a hexagon shape in the center.

If you allow line segments to be counted towards more than one triangle, then the number of triangles formed in the final symbol is 8, consisting of 2 large triangles and 6 smaller triangles.

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
