AD = DB

Angle ADE = Angle CDB

Angle DAE = Angle DBC (Alternate angles)

Angle DEA = Angle DCB (Alternate angles)

Since you have two congruent angles and one congruent side, triangle ADE is congruent to triangle CDB. This means that DE is congruent to DC implying D is the midpoint of CE.

The directions are with the pic below. It’s another pic coming. Couldn’t fit everything on the same page
Valentin [98]

Answer:

When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.

A(x,y)\Rightarrow A^{\prime}(-x,-y)

The coordinates are given below as

S(-1,3),T(-4,3),U(-3,1)

By applying the rule, we will have

\begin{gathered} S(-1,3)\Rightarrow S^{\prime}(-(-1),(-3)\Rightarrow S^{\prime}(1,-3) \\ T(-4,3)\Rightarrow T^{\prime}(-(-4),-3)\Rightarrow T^{\prime}(4,-3) \\ U(-3,1)\Rightarrow U^{\prime}(-(-3),-1)\Rightarrow U^{\prime}(3,-1) \end{gathered}

By graphing the triangle, we Will have
