What is a key characteristic of an isosceles right triangle?

• It has no equal sides

• It has a 90-degree angle and two equal sides

• All sides are equal

• It has two 60-degree angles

How can data be organized to identify patterns more easily?

• By organizing it in numerical order

• By arranging it randomly

• By using only the largest values

• By ignoring the smallest values
