1. Determina el recíproco: "Si los 3 ángulos de un triángulo son iguales, entonces el triángulo es isosceles". Escribe el reciproco, demuestra si se cumple o proporciona
un contraejemplo si no se cumple.
2. Determina el reciproco: "En el triángulo ABC, si AB = AC y AD es bisectriz de CAB
entonces AD es mediatriz de BC". Escribe el recíproco, demuestra si se cumple o
proporciona un contraejemplo si no se cumple.

answer: the correct answer is -32

step-by-step explanation:

• before the lesson, students attempt the assessment task individually. you then review students’

solutions and formulate questions that will them improve their work.

• during the lesson, students work collaboratively in pairs or threes, plotting graphs, completing

tables of values and deducing equations. then, based on the number of common solutions,

students link these representations.

• in a follow-up lesson, students receive your comments on the assessment task and use these to

attempt the similar task, approaching it with insights gained from the lesson.
