Step-by-step explanation:
1. No: angles add to more than 180 deg.
2. Yes: each side's length is between the sum and difference of the lengths of the other two sides.
3. No: not every side's length is between the sum and difference of the lengths of the other two sides.
4. Yes: for example, place the 50 deg angle between the two given sides. Another side will then make the triangle.
5. Yes: for example, use 3 cm as the short leg in a 30-60-90 right triangle.
Answer:
a and c are undefined.
b and d are zero.
Step-by-step explanation:
Vertical lines are undefined because of division by 0 (a and c).
The run is zero.
Horizontal lines have a slope of 0 (b and d).
The rise is zero.
