∙ 10y ago
By Definition, a triangle with two Congruent Sides is an Isosceles Triangle. For ALL angles to be Acute, that is, LESS than 90o , the two opposite angles must be greater than 45o.
Remember that the SUM of the angles in a Triangle must equal 180o.

Are two right triangles similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.
What type of triangle has exactly two acute angles?
An Isosceles Triangle.
Which triangle has two acute angles and one obtuse angle?
If you are classifying triangles by their angles, an obtuse triangle has one obtuse angle and two acute angles. A triangle can have at most one obtuse angle. If the two acute angles are congruent, the triangle would also be isosceles.
What is the definition to acute triangle?
A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.A triangle, all of whose angles are acute.
Name four different types of triangles?
Types of Triangles: By Sides: Isosceles- 2 congruent sides Scalene- no congruent sides Equilateral- 3 congruent sides By Angles: Acute- angles measuring less than 90° Obtuse- one angle measuring more than 90° Right- one angle measuring exactly 90° Equiangular- all angles measuring exactly the same- same as equilateral triangle
Does obtuse triangle have any angles congruent?
An obtuse triangle must have two acute angles and these can be congruent.
The acute angles of a right triangle are always congruent?
No.
A triangle containing 1 right angle and 2 congruent acute angles is called?
A triangle with 1 right angle and 2 congruent acute angles is both a right triangle and an isosceles triangle.
Two right triangles are similar if the acute angles of one triangle are congruent to the acute angles of the other triangle?
yes there similar
What type of triangle has no congruent sides but all angles are acute?
A scalene triangle
Are two right triangles similar if an acute angle of one triangle is congruent to an acute angle of the other triangle?
Yes, you have two congruent angles in each triangle, one right and one acute so the third angles must be equal also.
Classification of triangle?
Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.
Is an acute triangle ever regular?
Yes. An acute triangle has three acute angles so that would make it a regular polygon with congruent sides.
Do isosceles triangles have exactly two acute angles?
Answer: Yes, because of the two angles have to be exactly equal in order to be isosceles. And no isosceles has 3 acute angles and then it will be equilateral triangle Answer: No, the isosceles triangle can either have two acute angles, or all three can be acute.
What type of triangle has exactly two acute angles?
An Isosceles Triangle.
'True or false Two right triangles are similar if an acute angle of one triangle is congruent to an acute angle of the other triangle'?
Sounds true to me, all three angles are congruent...
A triangle that has three 3 acute angles is a what?
A triangle with 3 acute angles is an acute triangle. All the angles in an acute triangle are acute.
