Answer:

Step-by-step explanation:

statement   Reason

in ΔAOB and ΔCOD

BO=DO       (∵AC bisects BD)

AO=CO       (∵BD bisects AC)

∠AOB=∠COD (Vertically opposite angles)

ΔAOB≡ΔCOD (SAS )

∴∠A=∠C

Answer:

i havent done proofs in a while so i hope this makes sense? you should read over it and edit it if necessary.

i'm pretty sure it's supposed to be congruent triangles

1) AC bisects BD at O - given

2) AO=OC, DO=OB - def. of bisector (you can write these two seperately for both sides but don't think that's needed)

3) <AOB=<DOC - vertical angles

4) triangle AOB is congruent to triangle COD - SAS

5) <A is congruent to <C - CPCTC (corresponding parts of congruent triangles are congruent)

Two lines intersect in a plane in form for angles what are the angles formed fathers intersect is a 53° angle what are the measu
DedPeter [7]

Answer:

53°, 127°, 127°

Step-by-step explanation:

<u>Two intersecting lines form two pairs of angles:</u>

  • Pair of vertical angles. They are opposite to each other and are equal
  • Pair of adjacent angles which are supplementary angles and their sum is  180°

<u>So if one of the angles is measured 53°, then the other angles are:</u>

  • 53°- vertical angle with the first one
  • 180° - 53° = 127°
  • 180° - 53° = 127°
