to an object in his mind and recognize the change, describe a thing or

object in the mind and change it in a tangible form.

Sorby (2009) states that spatial ability is one type of intelligence that

is difficult to understand if the object studied is not familiar with student

life. However, some research results show that students' spatial abilities

can be improved by using computers. The presence of computer

equipment in the learning process of mathematics, including geometry,

whose object of study is abstract has an important role. Computers provide

new ways for students and teachers to present complex concepts and can

manipulate abstract objects with their own hands. The use of computers

allows students to process information directly in the form of multimedia

so that it will trigger students to actively select, organize, and integrate

visual and verbal information (Simanjuntak, 2013).

Computers are products of sophisticated technology to make it easier

for humans in doing their jobs. Through the use of computers, work

becomes more effective, efficient, and has better measurement accuracy

than manually. The use of technology in learning mathematics is effective,

especially in learning geometry (Ludwig, 1996). In geometry mathematics

learning, there are application programs that can be used to overcome the

less accurate depiction of mathematical objects, complex calculations and

spend a lot of time, and monotonous learning media, one of which is by

using Cabri 3D software.

According to Accascina and Rogora (2006), Cabri 3D is dynamic-

geometry software that can be used to help students and teachers to

overcome some difficulties and make learning three-dimensional geometry

(geometry of space) easier and more interesting. Cabri 3D is a Dynamic
