The answer is 5.
Step-by-step explanation:
To find the interquartile range you must look at the median and the upper and lower halves of the data. The median (12) to the upper half of the data (15) is 3. Next, look at the median (12) to the lower half of the data (10) it is 2. We then add 2 and 3 to get the interquartile range of 5.
Triangles are congruent when they have exactly the same three sides and exactly the same three angles.
The diagram shows two pairs of congruent triangle:
- triangle C is congruent to triangle E (have exactly the same three sides and exactly the same three angles);
- triangle D is congruent tot triangle F (have exactly the same three sides and exactly the same three angles).
Triangles A and B apears not to be congruent to any others triangles.
