Answer:
Step-by-step explanation:
The net of the triangular pyramid is attached below.
Since each of the faces is an equilateral triangle of side 6cm, the base of the pyramid will also be an equilateral triangle of side lengths 6cm .
In the equilateral triangles
Therefore, the surface area of the pyramid formed from the net shown
= 4 X Area of One Triangular Face

Answer:
SAS similarity theorem
Step-by-step explanation:
The diagram shows two triangles with congruent angles A and A'.
Consider the ratio of given sides:
As you can see, the ratio is the same.
<u>SAS similarity theorem</u> states that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar.
Hence, triangles ABC and A'B'C' are similar by SAS similarity theorem.
Wouldn’t it be C ? I think it’s c
