# Is a trangles a prallelogram?

no. a triangle is not a parallelogram. First of all, a parallelogram should be a quadrilateral, and quadrilateral forms are figures which has four sides.

secondly' a parallelogram should have two pairs of parallel sides. a triangle doesn't even have a pair of parallel sides.

No, they are equal. Adjacent angles are supplementary in a prallelogram.

A trapezoid has only 1 pair of parallel sides while a parallelogram has 2 pairs of parallel sides.

In general, the diagonals of a parallelogram are NOT the same length. They're equalonly when the parallelogram is either a rectangle or a rhombus (including square).

360 degrees, 90 degrees per angle, you can make two trangles inside of it, and triangles are 180 degrees

None; because there is no justification for assuming that the two triangles (or trangles, as you prefer to call them) are similar.

A parallelogram is a shape with 4 sides whose opposite sides are parallel. A rectangle meets this definition. It is a special type of parallelogram where the angles between sides all equal 90 degress.

The Pentagonal Rotunda has 20 vertices, 17 faces and 35 edges. The Pentagonal Rotunda contains 10 trangles, 6 pentagons and 1 decagon.

It's to do with The Greek mathematician called Pythagoras. He was into trangles, particulary right angles ones, where he came up with a theory that relates the lengths of each side in a right angle triangle.

The equation for pi can be given by estimating the circumference of a circle with infinitely many trangles through the use of limiting. The equation is:pi = limn->&acirc;&circ;&#382;(n(sin(180/n)))(Note: the notation -> is in this case an arrow)

A triangles' angles always equal 180 when all added up. So 180-150= 30 the last angle is 30 degrees.

A simple parallelogram is a square, but if you"bent" a square so the two sides were at, for example, a 30-degree angle to the base, it would still be a prallelogram. A parallelogram is a four-sided figure in which each pair of opposite sides are parallel.

They are both triangles that have interior degrees of 180 and exterior degrees of 360. An equilateral has three equal sides and three equal angles. An isosceles has two equal sides and two equal angles.

it is a trapezoid. Quadralaterals can be groups according to how many pairs of parallel sides they have. A square and a rectangle have all 4 sides parallel since they are parallelograms and by definition a prallelogram has two sets of parallel sides. A kite has no parallel sides.

The theory in right-angled trangles that the hypotenuse (The Side opposite the right angle) squared is equal to the the other 2 sides both squared, added together. So the formula for "Pythagorus Theorum" is a^2 + b^2 = h^2

Adjacent angles are those which are next to/part of a line segment. If you have a triangle ABC, it has three angles, A, B and C. Normally you assign the line segments, or sides of the trangles opposite the angles the same letter but in smaller case. So opposite angle A is side a, opposite angle B is side b, etc.So if you can draw that, you will see that side b will have two adjacent angles, A and C. Angle A wil be opposite of side b.Hope that helps. . ?!

If you have an equilateral triangle ABC, then draw the line from A to D, the mid point of BC. Then in trangles ABD and ACD, AB = AC (equilateral), BD = DC (D is midpoint), and AD is common so these two triangles are congruent and so angle ABD = angle ACD. That is, angle ABC = angle ACB. Similarly the third angle can be shown to be the same. Thus an equilateral triangle is also equiangular. Now, sum of the interior angles of any triangle is 180 degrees. So since sum of three equal angles measures is 180 degrees, they must be 60 degrees each, i.e. NOT 90 degrees so there is no right angle..
