w are the semicircle and the diameter of a circle related?
The length of the diameter and the length of semicircle are the same.
The degree measure of the diameter and the degree measure of the semicircle are the same,
The angle measure of the diameter is twice the angle measure of the semicircle,
The angle measure of the diameter is half the angle measure of the semicircle.

The degree measure of the diameter and the degree measure of the semicircle are the same.

Step-by-step explanation:

Diameter is the chord passing through the centre of the circle. It is the longest of all the chords of a circle. Semicircle refers to half circle. It is to be noted that semicircle has its base on the circle's diameter.

As we know that the angle measure of the diameter is 180 degrees (since diameter is also a straight line whose angle equals 180 degrees )

Similarly, the degree measure of the semicircle is half of the complete circle i.e. 360/2= 180 degrees.

Thus, angle subtended by the diameter is same as that of the angle made by the semicircle.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
