The triangles are congruent by the sss congruence theorem. which transformation(s) can map bcd onto wxy?

Translation then Rotation or Rotation then Translation

Step-by-step explanation:

We know that,

1. Rotation turns the figure around a point to a certain degree

2. Translation slides the figure in any direction

Now, it is given that the triangles BCD and WXY are congruent by SSS Theorem i.e. the corresponding three sides of both triangles are equal.

So, the only possible ways for the triangles to be congruent are:

I. If we first translate the figure BCD to the right and then rotate it counter-clockwise .i.e. Translation, then rotation.

II. If we first rotate the figure counter-clockwise and then translate the figure BCD to the right .i.e. Rotation, then translation.

Hence, either Translation then Rotation or Rotation then Translation maps BCD onto WXY.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
