Proving trapezoid theorems Geometry

ΔABD ≅ ΔACD by SAS, therefore;

by CPCTC

Step-by-step explanation:

The two column proof is presented as follows;

Statement                   Reason

ABCD is a trapezoid  Given

                    Given

                    Definition of a trapezoid

ABCD is an isosceles trapezoid      Left and right leg are equal

∠BAD ≅ ∠CDA            Base angle of an isosceles trapezoid are congruent

                   Reflexive property

ΔABD ≅ ΔACD           By SAS rule of congruency

                   CPCTC

CPCTC; Congruent Parts of Congruent Triangles are Congruent

SAS; Side Angle Side rule of congruency

Step-by-step explanation:

just did it

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
