Best Answer

Assuming you are referring to a triangle and are asking for one of the interior angle's measurements, this is the answer.

Because it is an equilateral triangle, the measures of the 3 angles are the same. They add up to 180 by the interior angles theorem.

Thus, the measure is 60 for each angle.

How can you prove a triangle ABC is isosceles if angle BAD is congruent to angle CAD and line AD is perpendicular to line Bc?

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)


Can you write a two column proof given angles 2 and 3 are congruent and prove angles 1 and 4 are congruent?

Without a visual or more information, I'm guessing that the picture is of angles 1 and 2 that are consecutive (share an angle side) and a separate picture of consecutive angles 3 and 4. With that said: 1) angle 2 congruent to angle 3................1) given 2) angle 1 is supplementary to angle 2....2) If angles are next to each other --> supps angle 3 is supplementary to angle 4 3) angle 1 congruent angle 4..............3) If supps to congruents angles ---> congruent


If angle 1 is congruent to angle 2 then?

angle 3 and 4 are complimentary


If two sides in a triangle are congruent then their opposite angles are?

Their opposite angle are equal and all 3 angles will add up to 180 degrees

When two shapes are similar does that mean they have the same amount of sides?

No, it means they have either 2 sides and 1 angle congruent, 2 angles congruent, 2 angles and a side congruent, or 3 sides congruent.


Is it possible to have two noncongruent triangles that have two pairs of congruent angle and one pair of congruent sides?

not possible, they only have 3 sides so they have to be congruent by ASA or AAS


Kinds of triangle according to number of congruent sides?

All triangles have 3 sides and 3 interior angles that add up to 180 degrees. Equilateral triangles have 3 congruent sides. Isosceles triangles have 2 congruent sides. A right angle triangle can have 2 congruent sides if its interior angles are 90, 45, 45 degrees. A scalene or an obtuse triangle has no congruent sides.

Are all sides of an isosceles triangle are congruent?

No because only 2 of its 3 sides are congruent in an isosceles triangle but all 3 sides of an equilateral triangle are congruent.
