Given:

Two triangles are congruent, i.e., [tex]\Delta ABC\cong \Delta XYZ[/tex].

To find:

All the measures of both triangle.

Solution:

We have,

[tex]\Delta ABC\cong \Delta XYZ[/tex].

We know that, corresponding parts of congruent triangles are congruent (CPCTC).

[tex]\angle A=\angle X[/tex]

[tex]\angle B=\angle Y=90^\circ[/tex]

[tex]\angle C=\angle Z=37^\circ[/tex]

It triangle ABC,

[tex]\angle A+\angle B+\angle C=180^\circ[/tex]     (Angle sum property)

[tex]\angle A+90^\circ+37^\circ=180^\circ[/tex]

[tex]\angle A+127^\circ=180^\circ[/tex]

[tex]\angle A=180^\circ -127^\circ[/tex]

[tex]\angle A=53^\circ[/tex]

So,

[tex]\angle A=\angle C=53^\circ[/tex]

[tex]AB=XY=3\text{ units}[/tex]

[tex]BC=YZ=4\text{ units}[/tex]

[tex]AC=XZ=5\text{ units}[/tex]

Therefore, m∠A = 53˚,  m∠B =90˚ , m∠C =37˚ , m∠X = 53˚,  m∠Y =90˚ , m∠Z =37˚ , Segment AB = 3 units , Segment BC = 4 units , Segment AC = 5 units , Segment XY = 3 units , Segment YZ = 4 units , Segment XZ = 5 units .
