Proof triangles

Mathematics

No, two sides the same is not enough.
You need more proof.

Side, angle, side. (SAS).
AD = DC
Angle ADB = Angle CDB
BD = BD

By the SAS property, the two triangles are the same.

I think this is one way to prove it...

Or, similarly...use ASA, (Angle, side, angle).

malfutka [58]

Answer:

∠ABC= 45°

Step-by-step explanation:

∠ABC= ∠BCD (alt. ∠s, AB//CD)

(2x +15)°= (3x)°

2x +15= 3x

3x-2x= 15 <em>(</em><em>-2x </em><em>on </em><em>both </em><em>sides)</em>

x= 15

Substituting the value of x:

∠ABC

= ∠BCD

= [3(15)]°

= 45°
