Are scalene triangles all obtuse?
No, a scalene triangle is simply a triangle where all angles are not equal and all side lengths are not equal, therefore they can or cannot be obtuse.
What has 4 sides 2 obtuse angles and 2 acute angles?
a triangle easy
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.
What are the characteristics of the different types of triangles?
All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are graded as follows:- Scalene triangle has 3 different acute angle Right angle triangle has a 90 degree angle and 2 acute angles Obtuse triangle has 1 obtuse angle and 2 acute angles Equilateral triangle has 3 equal sides and 3 equal angles of 60 degrees Isosceles triangle has 2 equal sides and 2 equal base angles
Does any obtuse triangle have a greater area than any acute triangle?
No.Finding an obtuse triangle that does not have a greater area than any acute triangle will show the statement is false:Consider the obtuse triangle with sides 25, 25, 40 cm; andthe acute triangles with sides 2, 2, 2 cm and 40, 40, 40 cmArea of (A) obtuse triangle = 40 x 12 ÷ 2 = 240 cm2Area of (B) acute 2, 2, 2 cm triangle = 2 x √3 ÷ 2 = √3 cm2 ~= 1.7 cm2Area of (C) acute 40, 40, 40 cm triangle = 40 x (20 x √3) ÷ 2 = 400 x √3 cm2 ~= 692.8 cm2So you can clearly see that area of acute triangle (C) is greater than that of obtuse triangle (B) which is greater than acute triangle (A).Thus the area of obtuse triangle (B) is not greater than that of any acute triangle.(Obtuse triangle A has angles approx 37o, 37o, 106o, whereas triangles B and C are equilateral acute triangles with angles 60o, 60o, 60o.)
Is a triangle with sides 10 14 10 obtuse acute or right?
it is an acute triangle.
What are the three triangles that are known for their sides?
right triangle , a obtuse triangle, and a acute triangle
How do you name a triangle?
The name of a triangle is dependent on the type of angles within it. If it has a right angle it is called a right triangle, if it has an obtuse angle it is an obtuse triangle, and if all three sides are acute it is an acute triangle.
What do the triangles look like and what are the names?
Equilateral triangle = All sides congruent Scalene triangle = No sides congruent Isosceles triangle = At LEAST two sides congruent Right triangle = Triangle with one right angle Obtuse triangle = Triangle with ONE obtuse angle Acute triangle = Triangle with ALL acute angles
What are the primary part of triangle?
scalene,acute obtuse,right
How do you name a triangle by its angles than its sides?
An acute angled triangle, right angled triangle or obtuse angled triangle.
A triangle has the sides of 13 15 and 17 Is it right acute or obtuse?
It's acute. Sum the squares of the shorter two sides and compare to the square of the longest side. If the sum is less, the triangle is obtuse. If they are equal, the triangle is right angle. If the sum is more, the triangle is acute. 132 + 152 = 169 + 225 = 394 172 = 289 Sum is more so triangle is acute.
What is triangle is an obtuse triangle?
An obtuse triangle is a type of triangle that has no congruent sides. Basically none of its sides are the same size.
What are the 6 possible groups of triangles?
Right triangle= has a right angle Acute triangle= has an acute angle Obtuse triangle= has an obtuse angle Equilateral triangle= all sides are the same length Scalene triangle= has no sides the same length Isosceles triangle= has only two sides the same length the triangles here make perfict dildose and condoms
How do you find out if a triangle is acute obtuse or a right triangle by the side lengths?
To determine if a triangle is acute, obtuse, or right based on its side lengths, you can use the Pythagorean theorem. For a triangle with sides (a), (b), and (c) (where (c) is the longest side), if (a^2 + b^2 = c^2), the triangle is right. If (a^2 + b^2 > c^2), it is acute, and if (a^2 + b^2 < c^2), it is obtuse.
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.
How do you determine a right acute obtuse triangle?
To determine if a triangle is right, acute, or obtuse, you can use the lengths of its sides. For a triangle with sides (a), (b), and (c) (where (c) is the longest side), apply the Pythagorean theorem: if (a^2 + b^2 = c^2), it’s a right triangle; if (a^2 + b^2 > c^2), it’s acute; and if (a^2 + b^2 < c^2), it’s obtuse. Alternatively, you can use the angles; a right triangle has one angle equal to 90 degrees, an acute triangle has all angles less than 90 degrees, and an obtuse triangle has one angle greater than 90 degrees.
