Geo final exam review
This geometry exam review covers topics that will be on the final exam. It includes true/false questions, multiple choice, matching, and free response problems involving geometry concepts like triangles, circles, polygons, and three-dimensional shapes. Calculators may be used but the exam may have non-calculator sections, so students should prepare with and without calculators. The review is due before the scheduled final exam date.
Exam view geotrig final s1 2011

The exam contains 66 multiple choice questions and provides diagrams when necessary to illustrate the questions being asked.
Lsn 11-8: Proving a Rhombus/Rectangle
To prove that a quadrilateral is a rectangle or rhombus, you must first prove that it is a parallelogram by showing that both pairs of opposite sides are parallel and congruent. Then, you need only one additional condition - either that the diagonals are congruent (rectangle) or that one angle is a right angle (rectangle), or that the diagonals are the same length (rhombus) or that one pair of consecutive sides are congruent (rhombus). The document provides an example proof of showing a quadrilateral is a rectangle.

Notes Day 6: Bernoulli Trials
This document defines Bernoulli trials and the binomial distribution. A Bernoulli trial is a random experiment with two possible outcomes: success or failure. A sequence of Bernoulli trials involves performing the experiment multiple independent times, keeping the probability of success the same. The binomial distribution calculates the probability of getting a certain number of successes in n Bernoulli trials. It satisfies properties where the experiment is conducted n times independently with a constant success probability p and failure probability of 1-p.

In fewer than 3 sentences, the document provides homework or class material on similar triangles and their corresponding sides.
Notes Day 4&5: Prove that Triangles are Similar
The document discusses three theorems for determining similarity of triangles:
1) The Angle-Angle Similarity (AA) Postulate states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar.
2) The Side-Angle-Side Similarity (SAS) Theorem states that if an angle of one triangle is congruent to an angle of a second triangle, and the sides including the two angles are proportional, then the triangles are similar.
3) The Side-Side-Side Similarity (SSS) Theorem states that if the corresponding sides of two triangles are proportional, then the triangles are similar.
Day 13-3: Similar Polygons

Egito antigo resumo - aula de história.pdf
O Egito Antigo foi formado a partir da mistura de diversos povos, a população era dividida em vários clãs, que se organizavam em comunidades chamadas nomos. Estes funcionavam como se fossem pequenos Estados independentes.
Por volta de 3500 a.C., os nomos se uniram formando dois reinos: o Baixo Egito, ao Norte e o Alto Egito, ao Sul. Posteriormente, em 3200 a.C., os dois reinos foram unificados por Menés, rei do alto Egito, que tornou-se o primeiro faraó, criando a primeira dinastia que deu origem ao Estado egípcio.
Começava um longo período de esplendor da civilização egípcia, também conhecida como a era dos grandes faraós.
