What is on my test??? True/False Finding congruent triangles and stating the postulate Find the value of x in triangles Median, altitudes, perpendicular bisector and hypotenuse 1 fill in the blank proof and one blank proof

CPCTC stands for congruent parts of corresponding triangles are congruent. FALSE Corresponding parts of congruent triangles are congruent.

The median of a triangle always lies inside the triangle. TRUE

The perpendicular bisector of a triangle goes through the midpoint of one side and the vertex of the opposite side. FALSE Only in Isosceles triangles.

The altitude of a triangle always lies inside the triangle. FALSE Obtuse triangles have altitude(s) are outside of the triangle.

The median is always perpendicular to a side of a triangle. FALSE A median is only perpendicular in an isosceles triangle. The median is drawn from the vertex of a triangle to the midpoint of the opposite side.

Two isosceles triangles will always be congruent to each other. FALSE

This is enough to prove congruency: TRUE HL postulate

In an isosceles triangle, the median and the altitude are the same line. TRUE That line is also the perpendicular bisector and angle bisector!

The perpendicular bisector is always drawn from the vertex of a triangle to the midpoint of the opposite side. FALSE Median!

This is an isosceles triangle: TRUE

Name my 5 triangle postulates:
