all triangles have three corners. An isosceles triangle also has two sides and atwo angles that are equal.
an isosceles has only 1 line of symmetry
i you cant answer that, you must be in kindergarden. Anyway, a polygon is a 2-D figure with sides that do not intersect, are not curved, and all touch each other. A triangle is a type of polygon with...well...the root tri inplies it has three of something. the word angle says it has angles. so it has three angles. if it has three angles it has three sides. durr. /\ A triangle ==> / \ / \ --------
A trapezium doES have 4 angles.
Three EdgesA triangle has three edges.
all triangles have three corners. An isosceles triangle also has two sides and atwo angles that are equal.
none
scalene triangle dose not have any equal sides or angles =)
3 angles
None, by definition
an isosceles has only 1 line of symmetry
Iso (same) Skelos (leg, implies side) triangle has 2 equal sides (at least), and hence has 2 equal angles (at least).An equilateral triangle (all 3 sides are equal in length, and all 3 angles are equal, which means 600 each in 3600, or PI/3 with 2PI = 360 degree ) is a special family (class) of isosceles.It has:Two equal sidesTwo equal angles♥s' Barbiee doll☺
3 2 pararell 1 base
Yes it dose.
It has 2 pairs of opposite equal angles which are acute and obtuse.
something that has 2 sides the same. and one different. if u have heard of the 'isoceles triangle'
Yes, it has to in order to be a triangle.
