A quadrilateral is a parallelogram if a pair of opposite sides is equal and parallel prove?
A quadrilateral is a parallelogram if one pair of opposite sides are equal and parallel Let ABCD be a quadrilateral in which ABCD and AB=CD, where means parallel to. Construct line AC and create triangles ABC and ADC. Now, in triangles ABC and ADC, AB=CD (given) AC = AC (common side) Angle BAC=Angle ACD (corresponding parts of corresponding triangles or CPCTC) Triangle ABC is congruent to triangle CDA by Side Angle Side Angle BCA =Angle DAC by CPCTC And since these are alternate angles, ADBC. Thus in the quadrilateral ABCD, ABCD and ADBC. We conclude ABCD is a parallelogram. var content_characters_counter = '1032';
If ABCD is a rectangle and mCBD 47 what is the value of x?
In rectangle ABCD, angle CBD is given as 47 degrees. Since opposite angles in a rectangle are equal and adjacent angles are supplementary, angle ABC (adjacent to CBD) would be 180 - 47 = 133 degrees. Therefore, if x represents the measure of angle CBD, then x = 47 degrees.
What is the simplified version of a times b times c?
The product can be expressed as abc.
If one pair of sides of a quadrilateral is parallel and congruent then the quadrilateral is a parallelogram?
== == yes. suppose the quad ABCD has AB and CD equal and parallel. Then the triangles ABC and CDA are congruent by SAS axiom; so the quad is a parallelogram
What are the lengths of the diagonals of the quadrilateral abcd when ab is 4.3 cm bc is 3.4 cm cd is 3.8 cm angle abc is 95 degrees and angle bcd is 115 degrees?
If you mean quadrilateral ABCD then by using the cosine rule diagonal AC equals 5.71 cm and diagonal BD equals 6.08 cm both rounded to two decimal places.
The parallelogram ABCD is a rhombus what type of triangle is ABC?
isosceles triangle
If ABCD is a parallelogram and the two diagonals are equal find the measure of angle ABC?
90 degrees - the parallelogram is a rectangle (or a square) if the diagonals are equal.

Prove diagonals are equal in a rectangle?
Suppose ABCD is a rectangle.Consider the two triangles ABC and ABDAB = DC (opposite sides of a rectangle)BC is common to both trianglesand angle ABC = 90 deg = angle DCBTherefore, by SAS, the two triangles are congruent and so AC = BD.

Where can one one find a schedule for the ABC family channel?
One can find a schedule for the ABC Family channel online on the the ABC Family website. Schedule for the ABC Family channel may also be available in one's local newspaper.
What is the angle adc in the quadrilatera abcd when angle abc is 90 degrees and its sides are ab is 3 cm bc is 4 cm cd is 7.4 cm da is 4.3 cm?
If you mean quadrilateral ABCD then by using Pythagoras' theorem diagonal AC is 5 cm and using the cosine rule angle ADC works out as 41.04 degrees.
