i dont know the anwser to this iand i really need it for my homwork

given ab is congruent to dc, ab is parrallel to dc, bc is congruent to ce, prove abc congruent to dce

My math teacher and numerous online websites state that a cube has 11 nets. But none of them give a mathematical proof as to why that is. I believe this statement is not important enough for...

In ΔABC shown below, ∠BAC is congruent to ∠BCA: Triangle ABC, where angles A and C are congruent Given: Base ∠BAC and ∠ACB are congruent. Prove: ΔABC is an isosceles triangle. When completed...

I'm a communication major who is terrible at math and desperate for help :<   Picture of the diagram  https://imgur.com/1fPA51t ;

I have no clue on how to do this. I really need help filling out a 2 collum proof

I a'm supposed to prove that segment ls of parallelogram lens is parallel to segment gt of parallelogram gthn in 4 steps given that lens and gthn are parallelograms. I don't quite know how....

Let H be the orthocenter of a triangle ABC. Let M be the midpoint of BC, and let E, F be the feet of the B and the C altitudes onto the opposite sides. Let X be the intersection of ray MA with the...

Given: triangle ACB, segment AC is congruent to segment BC and angle ADB is congruent to angle BEA

given : line bf is perpendicular to line ac line ce is perpendicular to line ab line ae is congruent to line af

Define a function F: L TO R by F(A)= PA+QA for each point A in L. Find the point in L at which F achieves its minimum.

1. E is the midpoint of AC and BD 2. The measure of angle ABC + angle BCD = 180 degrees 3. AB is parallel to DC, and BC is congruent to DA 4. Angle ABC is congruent to angle ADC, and...

Given: L is parallel to M ; M is parallel to N   Proof: angle 1 is congruent to angle 12 I don't know how to do this and the Teacher didn't clarify how to correctly do it so I'm...
