(63) Man it was a educated guess to proud of myself dis answer is by Tamika Stem
Without seeing the picture, I can't tell what's already known to be congruent, so there's no way I can figure out what 'else' is needed.
A = 60 B = 20 C = 140 This can have a large number of answers.
the answer is 68 degrees
Angle ABD = 4x - 4 Angle ABC = twice angle ABD = 7x + 4 So 7x + 4 = 2*(4x - 4) = 8x - 8 So x = 12 Then angle DBC = half of angle ABC = 1/2*(7*12 + 4) = 1/2*88 = 44 degrees.
if you read this you smell :p
Measure it, or if it is marked by a letter or number and a different shape has the SAME letter or number then the angles are congruent. A congruent angle are angles that have the same measure. Thye sign that is used to show this is ~=(~on top of the =). For example, ABC ~=PQR. This means that angle ABC has the same measure as PQR.
Angle "A" is congruent to Angle "D"
A triangle if not found congruent by CPCTC as CPCTC only applies to triangles proven to be congruent. If triangle ABC is congruent to triangle DEF because they have the same side lengths (SSS) then we know Angle ABC (angle B) is congruent to Angle DEF (Angle E)
Yes. if triangle ABC maps to triangle A'B'C'. then AB = A'B', BC = B'C' and AC = A'C'. By SSS, triangle ABC is congruent to triangle A'B'C'. Since corresponding parts of congruent triangles are congruent angle A = angle A'. The correct spelling of the term for a length preserving transformation is "isometry" not "isometery".
Statement Reason1. triangle ABC is equilateral..............................................given2. AC is congruent to BC;AB is congruent to AC........................................definition of equilateral3. angle A is congruent to angle B;and B is congruent to angle C.............................Isosceles Theorem4. angle A is congruent to angle C..................Transitive Property of Congruence5. triangle ABC is equiangular...............................Definition of equiangular
The sum of the two angles is 360. So angle ABC = 120 degrees.
Given: AD perpendicular to BC; angle BAD congruent to CAD Prove: ABC is isosceles Plan: Principle a.s.a Proof: 1. angle BAD congruent to angle CAD (given) 2. Since AD is perpendicular to BC, then the angle BDA is congruent to the angle CDA (all right angles are congruent). 3. AD is congruent to AD (reflexive property) 4. triangle BAD congruent to triangle CAD (principle a.s.a) 5. AB is congruent to AC (corresponding parts of congruent triangles are congruent) 6. triangle ABC is isosceles (it has two congruent sides)
Line segment BC is congruent to Line Segment YZ
angle B angle Y (Tested, correct) Nicki is not the answer, just ignore that.
Angle in triangle abc measure 27, 73 and 80, what kind of triangle is abc
Oh, dude, if ABC DEF, then congruences like angle A is congruent to angle D, angle B is congruent to angle E, and side AC is congruent to side DF would be true by CPCTC. It's like a matching game, but with triangles and math rules. So, just remember CPCTC - Corresponding Parts of Congruent Triangles are Congruent!
