What is right angle DEF?
It is an angle measuring 90 degrees.
What is the vertex of the angle DEF?
The letter E would be at the vertex. The two lines enclosing the angle E would be ED and EF. Usually, to make it quite clear we would call angle E by the description "angle DEF or angle FED (they are the same angle).
What are congruence theorems and postulates?
If the sides AB, BC and CA of triangle ABC correspond to the sides DE, EF and FD of triangle DEF, then the two triangles are congruent if:AB = DE, BC = EF and CA = FD (SSS)AB = DE, BC = EF and angle ABC = angle DEF (SAS)AB = DE, angle ABC = angle DEF, angle BCA = angle EFD (ASA)If the triangles are right angled at A and D so that BC and EF are hypotenuses, then the triangles are congruent ifBC = EF and AB = DE (RHS)BC = EF and angle ABC = angle DEF (RHA).
Which are the acute angle in triangle DEF?
They are the angles that are greater than 0 but less than 90 degrees
Can a right angle labeled def also be called fed?
Yes, as long as the label for the vertex stays in the middle, you can read it in any direction you want.
what is the scale factor from ABC to DEF?
Answer: Since you are looking for the scale factor of ABC to DEF the answer is 8 because DEF is 8 times larger than ABC.
If ABC def and the scale factor from ABC to def is what are the lengths of and respectively?
4,8,12
What is the scale factor of abc def?
6 apex
What is the scale factor of ABC and DEF?
the answer would be 10 0n apex
If ABC DEF and the scale factor from ABC to DEF is 17 what are the lengths of DE EF and DF respectively?
They are 17 times AB, BC and Ca, respectively.
What is another name fpr right angle DEF?
Angle DEF is the same as angle FED.
In triangle DEF DE equals 5 and measure of angle D is 55 degree's find Fe to the nearest tenth?
in triangle def side de equals 5 and angle d equals 55 find fe
What is the scale factor of triangle ABC 81216 and triangle DEF 101520?
If you mean: 8 12 16 and 10 15 20 then it is 4 to 5
What describe an angle with a vertex at E?
FED and DEF lol
What is right angle DEF?
It is an angle measuring 90 degrees.
How do you find a triangle congruent by cpctc?
A triangle if not found congruent by CPCTC as CPCTC only applies to triangles proven to be congruent. If triangle ABC is congruent to triangle DEF because they have the same side lengths (SSS) then we know Angle ABC (angle B) is congruent to Angle DEF (Angle E)
Angle abc is congruent to angle def Angle A is 22 degrees Angle D is 5y-3 degrees Find x y Given are the hypotenuse of 9 and 3x?
Angle_abc_is_congruent_to_angle_def_Angle_A_is_22_degrees_Angle_D_is_5y-3_degrees_Find_x_y_Given_are_the_hypotenuse_of_9_and_3x
