Sides
A triangle that has no congruent sides.
What is a scalene triangle?
A triangle with a 90 degree angle.
What is a right triangle?
Use this postulate to prove triangles are congruent:
2 triangles have right angles, congruent hypotenuse, and 1 congruent leg.
What is the HL Postulate?
If three sides of one triangle are congruent to three sides of a second triangle, then the two triangles are congruent.
What is SSS?
It is a triangle with two congruent sides.
What is an Isosceles Triangle?
This triangle has 3 congruent sides.
A triangle with 3 congruent angles.
What is an equiangular triangle? (Also will take: What is an equilateral triangle?)
Use this postulate to prove congruent:
2 triangles have a right angle, one congruent acute angle, and a congruent hypotenuse.
What is HA Postulate?
If two sides and the included angle of one triangles are congruent to two sides and the included angle of a second triangle, then the two triangles are congruent.
What is SAS?
It is a triangle with three acute angles.
What is an acute triangle?
This Triangle has 2 congruent sides.
What is an isosceles triangle?
A triangle with two congruent angles.
What postulate show congruent:
2 right triangles have congruent acute angle and congruent leg
What is LA postulate?
2 triangles have 2 congruent angles and the included sides are congruent.
What is ASA?
It is a triangle with one obtuse angle.
What is an Obtuse Triangle?
It is the side opposite of the right angle in a right triangle.
What is the Hypotenuse?
The angles inside of a triangle.
What are interior angles?
This postulate can prove triangles congruent if two legs of 2 triangles are congruent and they have 90 degree angles.
What is LL Postulate?
In Triangle PQS and Triangle WXY, segment PQ is congruent to WX, Angle Q is congruent to Angle X, and segment QS is congruent to XY. Then the triangles are congruent by this postulate.
What is SAS postulate?
Property that says every triangle is congruent to itself.
What is the Reflexive Property?
The non-congruent side of an isosceles triangle is called this.
What is the base of the triangle?
The measure of each angle in an equilateral triangle?
What is 60 degrees?
Two triangles with congruent hypotenuses and a congruent leg are congruent by this postulate.
What is HL Postulate?
What is ASA Postulate?
If a triangle is equilateral then it is also this.
What is equiangular?
