Answer: Only one.
Step-by-step explanation:
Let Δ ABC be a right isosceles triangle with two sides are 4 inches and the angle between them is 90°.
Then all the triangles with same measurement will be congruent to Δ ABC by SAS congruency criteria .
Therefore, there is only one triangle possible for the given measurement.
- The SAS postulate says that if two sides and the included angle of a triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.
