Answer: AB will be parallel to A'B'.
Step-by-step explanation: We know the definition of dilation about the centre. It is defined as the enlargement or shrinken of the original figure keeping the centre of dilation or the figure as fixed.
We are given ΔUVW and AB is perpendicular to UW. Now, if we dilate the triangle about the origin, then the triangle will either enlarge or shrink keeping the centre fixed.
Let us consider the enlarged triangle, ΔU'V'W' as shown in the attached figure. Also, line AB will move to the new position A'B'. We can clearly see that both the lines are parallel to each other.
Thus, the line segments AB and A'B' will be parallel too each other.
Answer:
the square root of 1521 is 39 and 390 squared is 152,100 if that helps you
Answer: a^8-b^8
Step-by-step explanation:
A regular triangular pyramid is a solid figure with r surfaces
- 3 lateral surfaces and one base surface
- the four surfaces are congruent triangles, which is to say that all triangular surfaces have the same base and the same slant heght
- the area of each surface is [1/2] base * slant height.
Then, a change that double the area is any that keep one of the dimensiones and double the other.
So the answer is: double each side, b, of the base triangle while keeping the slant height, l, tha same.
You can also double the slant height, l, while keeping the base triangle, but then the height,h, of the pyramid will increase, by a factor which is not 2.
