1. An acute angle is defined as an angle measuring less than 90 degrees.
2. An isosceles triangle has exactly two equal sides, not three.
3. An equilateral triangle has three 60-degree angles, all of which are acute (less than 90 degrees).

Step1: Calculate total pages read on nights 1+3

$137 + 250 = 387$

Step2: Subtract from total book pages

$677 - 387 = 290$

Answer:

1. True
2. False
3. True

(For drawing an acute angle: Sketch two rays sharing a common endpoint, forming an angle smaller than a right angle, e.g., a 45-degree angle.)
