Do all triangles have two acute angles?
INCORRECT: No because there is a obtuse triangle and a right triangleCORRECT ANSWERYes all triangles have at least two acute angles. Obtuse triangles and right triangles also have at least two acute angles. They are called obtuse triangles and right triangles because by definition they are triangles with ONE obtuse angle and ONE right angle. So therefore they both have 2 acute angles. Also for an acute triangle, it would have 3 acute angles.
Do triangles have at least one right angle?
Triangles can be classified by their sides or their angles. When classifying them by their angles, triangles are called: acute triangles - all three angles are acute (less than 90º) right triangles - one right angle (90º) and two acute angles obtuse triangles - one obtuse angle (larger than 90º) and two acute angles
How can you classify triangles by their angles?
Triangles may be right triangles equilateral triangles acute or obtuse triangles
Are all acute and right triangles similar?
no
What shapes have acute and right angles?
Triangles
How many acute angles are in a right triangles?
In a right triangle there is only one acute angles.
Which are congruence theorems for right triangles?
The congruence theorems for right triangles are the Hypotenuse-Leg (HL) theorem and the Leg-Acute Angle (LA) theorem. The HL theorem states that if the hypotenuse and one leg of one right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent. The LA theorem states that if one leg and one acute angle of one right triangle are congruent to one leg and one acute angle of another right triangle, then the triangles are congruent.
Are all scalene triangles acute triangles?
No, scalene triangles can be obtuse, right or acute triangles. A 3 - 4 -5 right triangle (lengths of the sides) is one example of a right-scalene triangle. In fact, with the exception of the [45°, 45°, 90°] right triangle (which is isosceles) all other right triangles are scalene.
Are Isosceles triangles right obtuse and acute?
yes a isosceles triangle has a right,obtuse and acute angle.
Do acute triangels have right angels?
No because only right angle triangles have 2 acute angles
Do all right triangles have acute angles?
All right angle triangles have a 90 degree angle and two acute angles that add up to 90 degrees
Right triangle and acute triangle are the same?
No. All three angles of an acute traingle are less than 90 degrees, so it cannot be a right triangle. The only similarity between them is that right angle triangle has 2 acute angles while acute triangles has 3 acute angles
