Oh honey, that's an easy one. Another name for a right angle DEF is a 90-degree angle. It's like the perfect L shape, straight up and down, no funny business. So, go ahead and call it a 90-degree angle or a right angle, whatever floats your boat.
FED and DEF lol
Angle "A" is congruent to Angle "D"
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)
in triangle def side de equals 5 and angle d equals 55 find fe
D=27 E=81 F=72
Angle DEF is the same as angle FED.
Right angle E
We are not here to do your homework for you.
It is an angle measuring 90 degrees.
It will be a right angle triangle with a 90 degree angle and 2 acute angles
FED and DEF lol
To find the scale factor of angle PRQ to angle DEF, you first need to determine the measures of both angles. The scale factor is then calculated by taking the ratio of the measures of angle PRQ to that of angle DEF. For example, if angle PRQ measures 30 degrees and angle DEF measures 60 degrees, the scale factor would be 30:60, which simplifies to 1:2.
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).
wheat belt def.
Yes, triangles ABC and DEF are congruent if all corresponding sides and angles are equal. The congruence postulate that applies in this case could be the Side-Angle-Side (SAS) postulate, which states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent. Other applicable postulates include Side-Side-Side (SSS) and Angle-Angle-Side (AAS), depending on the known measurements.
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).
Yes, as long as the label for the vertex stays in the middle, you can read it in any direction you want.
