Determine whether side-angle-angle (saa) is a valid means for establishing triangle congruence. in this case, you know the measure of a side, an adjacent angle, and the angle opposite to the side. if it is a valid criterion, explain why. if it is not valid, use geogebra to create a counterexample demonstrating that it doesn’t work and give an explanation. if you construct a counterexample, take a screenshot of your work, save it, and insert the image in the space below.

Basically if you know side-angle-anlge, you can determine the third angle by

3rd angle = 180 - angle 1 - angle2

In this way, you are using the Angle-Side-Angle method of congruence.

Step-by-step explanation:

Answer with explanation:

→If you know two angles and one side of triangle ,the two triangles are congruent by Axiom called AAS, because third angle can be obtained by angle sum property of triangle.So, AAS , SAA or ASA are same thing.

→So, Instead of SAA, the axiom which is used that is named to prove congruence of triangles is AAS or ASA--Angle Angle Side or Angle Side Angle.

→Mathematicians have named AAS or ASA as congruence criterion of two triangles, but if you will write SAA, it will be also valid unles and otherwise the teacher should have good knowledge of mathematics.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

may i see the picture? it would a lot, xox
