a,what is a triangle ? write a definition.A triangle is a flat shape formed by threeStaight lines that intersect each other.It has three sides and three vertices. Its Angles add up to 180º.

b,describe the characteristics of a quadrilateral.what quadrilaterals can youName?Quadrilaterals are flat shapes that have Four straigth sides , two of which intersect The other two.They have four sides and four angles and theSum of the angles is 360º.

c,name and define the important lines of aTriangle.The important lines of a triangle are :Heigth , middle point & middle point of a Segment .Heigth : this is measured perpendiculary to the Base in a straigth line to its opposite vertex .Middle point : is the middle point of any side of A triangle .Middle point of a segment : this is the line thatJoins any vertex in a triangle to the middle Point of its opposite side .

d,what is a trapezoid? How is it different from Quadrilaterals called parallelograms.

A trapezoid is is a quadrilateral that none of Its sides are equal nor paralel . And its angles And diagonals are different . The angles are Not rigtht-angles and the diagonals are not Parallel.It is different from the cuadrilaterals called Parallelograms because the parallelograms.Because all the things are different .

Trapezoid parallelogram

e,draw the following triangles and Quadrilaterals giving step-by-step diagrams.Write simple instructions for each step.1.a triangle with sides that mesure 65,55 and45mm.2.a diamond with the longest diagonal Measuring 60mm and its smallest diagonalMeasuring 50mm.3.a trapezoid with sides measuring
