The document contains three summaries: 1) It instructs students to write out four geometry terms 10 times each as bell work and that it will be collected in 2 minutes. 2) It introduces the Hypotenuse-Leg Postulate which states that if the hypotenuse and one leg of one right triangle are congruent to the corresponding parts of another right triangle, then the two triangles are congruent. 3) It provides an example proof using the Hypotenuse-Leg Postulate and assigns an exit slip problem and homework problems for students due on Friday.

BELL WORK: On a sheet of notebook paper, write each of
the following words 10 times. Please spell them correctly, or
you will not receive credit:
• vertical
• isosceles
• equilateral
• equiangular
I will collect this 2 minutes after the bell rings.
3.8 ­ HL Postulate
HL Postulate: If there exists a correspondence between the vertices of two right triangles
such that the hypotenuse and a leg of one triangle are congruent to the corresponding
parts of the other triangle, the two right triangles are congruent.
Let's re­word that more simply!
