Question

Can someone please help me finish this problem? Will fan and medal

Answer 1

@DanJS

Answer 2

@narcissistic

you can see that the 2 triangles SHARE the side at the bottom of the drawing

THAT is the key to the proof you need (SAS)

BTW you are unlikely to get useful help from @koolklue22 - be very careful of accepting anything he/she writes

Answer 3

Okay, but how do I write that?

Answer 4

Look into the Reflexive Property of Equality because it should help with this. Then look at what parts you have that are congruent.

Answer 5

You need to fill in one line of the table to show that the triangles are congruent by SAS rule.

It already tells you that the 2 long sides and the angle are congruent.

The other side is CI and is common to BOTH triangle

so fill in the line saying CI is shared/equal/the SAME

The last empty space is SAS

You must look at this and understand it - it is no use just copying what I write.

If 2 triangles have two sides and the included angle which are congruent, then the triangles are congruent (SAS rule)
