If two sides of a triangle are of equal lengths what does that say about the angles opposite those sides?
The base angles of an isosceles triangle that has two equal sides are equal.
Are all triangles equilateral?
No.Equilateral triangles must have equal angles (all 60 degrees) and equal length sides; there are also:Isosceles triangles which have two equal angles and two equal sides;Scalene triangles which have all three sides, and hence all three angles, of different lengths;Right angled triangles (which can have all sides of different lengths, or two sides of equal length) have (as the name suggests) one right angle. This means Pythagoras and the trigonometric ratios can be used on its side lengths.
If 3 corresponding angles of two triangles are of equal measure are the side lengths of equal measure also?
Not necessarily. You have described "similar" triangles. If you also know that any of the lengths of sides are of equal measure in addition to three angles (congruent), then the lengths of all of the sides are of equal measure. But with what you have given, consider, for example, two equilateral triangles, both have all angles equal to 60 degrees (satisfying the condition in your question). One of the triangles could have sides length 1 and the other with sides all of length 2.
Is there 4 angles in a parallelogram?
Yes, a parallelogram has four sides and four internal angles, the opposite side lengths are equal and the opposite angles are equal.
What facts about isosceles trapezoid?
It is a 4 sided quadrilateral Its base angles are equal in size It has 2 equal acute and 2 equal obtuse angles Its 4 angles add up to 360 degrees It has a pair of parallel sides of different lengths It has 1 line of symmetry Its perimeter is the sum of its 4 sides Its area is 0.5*(sum of parallel sides)*height
What in a equalateral triangle is equal besides the three sides?
As well as the the 3 sides of an equilateral triangle being equal in lengths so are its 3 interior angles equal in angles of 60 degrees.
What is attributes of a equilateral triangle?
looawawer The sides are of equal lengths and the internal angles are each 60 degrees.
How do you find out the angles of of equilateral triangles?
Any equilateral triangle has 3 sides of equal lengths and 3 equal interior angles of 60 degrees. 3*60 = 180 degrees.
What is the difference between squares rhombuses and rectangles?
Squares have four sides of equal length and four right angles.Rhombuses (rhombi) have four sides of equal length but the angles are not right angles. Rectangles have four right angles but the sides are not all of the same length.
What is a quadrilateral with 2 pairs of congruent sides which none equal 90 degrees?
A square, rectangle, or parallelogram. Depends on the angles and the lengths of the sides.
Is it true if a regular polygon will have equal sides lengths but not have equal angles?
No.A regular polygon has equal side lengths and equal angles.
If all sides have equal lengths and angles are equal what is it called?
Equilateral? * * * * * No. Equilateral means only that the sides have equal lengths - not that the angles are also equal. A rhombus, for example is equilateral but not equiangular. The correct answer is "regular".
If two sides of a triangle are of equal lengths what does that say about the angles opposite those sides?
The base angles of an isosceles triangle that has two equal sides are equal.
Are all triangles equilateral?
No.Equilateral triangles must have equal angles (all 60 degrees) and equal length sides; there are also:Isosceles triangles which have two equal angles and two equal sides;Scalene triangles which have all three sides, and hence all three angles, of different lengths;Right angled triangles (which can have all sides of different lengths, or two sides of equal length) have (as the name suggests) one right angle. This means Pythagoras and the trigonometric ratios can be used on its side lengths.
4 sides equal angles not 90 degrees?
If all 4 sides are equal and the angles are not 90 degrees it is a rhombus.
How does a picture of a scalene acute triangle look like?
A scalene acute triangle is a triangle with all sides of different lengths and all angles less than 90 degrees. It does not have any equal sides or equal angles. Therefore, a picture of a scalene acute triangle would show three lines of different lengths connecting to form a triangle with three angles less than 90 degrees.
What is a figure with sides that have equal lengths and all the angles have equal measures?
polygon
