Answer:

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180 so the third angle in the first triangle is 180 - 60 - 40 = 80

The value of x is 40 because given triangles are have two pair of angles that are equal.

Answer:

SAS means "Side, Angle, Side"

ASA means "Angle , Side, Angle"

AAS means "Angle, Angle, Side"

HL stangs for "Hypotenuse, Length"

Step-by-step explanation:

SAS is when we have two sides meeting and forming an angle between them.

ASA is when we know two angles and a side between the angles.

AAS is when we know two angles and a side which is not between the angles.

HL means that: two triangles are congruent if the hypotenuse of one triangle is equal to the hypotenuse of the other and if one leg of a triangle is equal to a leg of another triangle.
