What is triangle and who many types of triangle?
A triangle is a 2-dimensional closed shape (called a polygon) with 3 sides. The three sides form a closed shape with three interior angles, hence the name "tri-angle." There are three general types of triangles: they are called Acute, Obtuse, and Right Triangles. Acute Triangles contain interior angles that are all less than 90 degrees. Obtuse Triangles contain one (and only one) interior angle that is greater than 90 degrees. Right Triangles contain one (and only one) angle that is exactly 90 degrees. There are also sub-types of triangles; the most common sub-types are Equilateral and Isoscles Triangles. The interior angles of Equilateral Triangles are all 60 degrees. At least two interior angles of Isoscles Triangles are equal to each other.
What is a acute trianlge?
an acute triangle is a triangle that has corner angles all below 90 degrees. there are three types of triangles: obtuse, right, and acute. obtuse triangles have one corner angle greater than 90 degrees, right triangles have one angle equal to 90 degrees, and acute triangles have all corner angles less than 90 degrees.
Are all the triangles similar?
No because there are different types of triangles but they all have 3 sides and 3 inside angles that add up to 180 degrees
How many degrees total the degrees total the sum of any triangles?
There are 180 degrees in any and all triangles.
How many types of triangles are there and how many shapes are there all together?
There are countless number of shapes and triangles. Some different types of triangles are iscoleses, right and scalene. Some shapes are circle, triangle, square, hectagon, octagon, prism.....the list goes on and on and on......
Are some right triangles also equilateral triangles?
no because an equilateral triangle has 3 sides that have equal angles and is not 90 degrees
Do some equilaterall triangles have angles?
All equilateral triangles have 3 equal interior angles each measuring 60 degrees
What is triangles complete degrees?
180 degrees
How are isosceles triangles and scalene triangles in common?
-- both types of triangle are plane (2-dimensional) figures-- both types of triangle have three sides-- both types of triangle have three interior angles that add up to 180 degrees-- in both types of triangle, sin(A)/a = sin(B)/b = sin(C)/cThose are the only characteristics shared by isosceles and scalene triangles.
What is the sum of the angle measures in a regular hexagon?
A hexagon has 6 triangles inside of it. If one triangle equals 180 degrees and there are 6 triangles. 180 degrees *6 triangles=1080 degrees.
What does all the triangles look like and what type of triangle are they?
There are infinitely many types of triangles, and they can be classified according to their angles or sides (or both). Equilateral (equiangular triangles): All sides equal, all angles 60 degrees. Obtuse angled isosceles triangles: Two sides equal; one angle > 90deg. Right angled isosceles triangles: Two sides equal; angles of 90, 45, 45 degrees. Other isosceles triangle: Two sides equal; angles of 180-2x, x, x degrees. Obtuse angled scalene triangles: All sides unequal, one angle > 90 degrees. Right angled scalene triangles: All sides unequal, one angle = 90 degrees. Acute angled scalene triangles: All sides unequal, all angles < 90 degrees.
What is a triangles isosceles or a scalene?
They are both types of triangles
